Washington, D.C., formally theDistrict of Columbiaand commonly known asWashingtonorD.C., is thecapital cityandfederal districtof theUnited States. The city is on thePotomac River, across fromVirginia, and shares land borders withMarylandto its north and east. It was named forGeorge Washington, the firstpresident of the United States. The district is named forColumbia, the femalepersonification of the nation.

TheU.S. Constitutionin 1789 called for the creation of a federal district under theexclusive jurisdictionof theU.S. Congress. As such, Washington, D.C., is not part of anystate, and is not one itself. TheResidence Act, adopted on July 16, 1790, approved the creation of thecapital districtalong the Potomac River. The city was founded in 1791, and the6th Congressheld the first session in the unfinishedCapitol Buildingin 1800 after the capital moved fromPhiladelphia. In 1801, the District of Columbia, formerly part of Maryland and Virginia and including the existing settlements ofGeorgetownandAlexandria, was officially recognized as the federal district; initially, the city was a separate settlement within the larger district. In 1846, Congressreturned the land originally ceded by Virginia, including the city of Alexandria. In 1871, it created asingle municipalityfor the remaining portion of the district. There have been several unsuccessfulefforts to make the district into a statesince the 1880s; astatehood billpassed theHouse of Representativesin 2021 but was not adopted by theU.S. Senate.

Designed in 1791byPierre Charles L'Enfant, the city is divided intoquadrants, which are centered around the Capitol Building and include 131neighborhoods. As of the2020 census, the city had a population of 689,545.^[3]Commuters from the city's Maryland and Virginia suburbs raise the city's daytime population to more than one million during the workweek.^[12]TheWashington metropolitan area, which includes parts of Maryland, Virginia, andWest Virginia, is the country'sseventh-largest metropolitan area, with a 2023 population of 6.3 million residents.^[6]A locally elected mayorand13-member councilhave governed the district since 1973, though Congress retains the power to overturn local laws. Washington, D.C., residents are, on the federal level,politically disenfranchisedsince the city's residents do not have voting representation in Congress; the city's residents elect a singlenon-voting congressional delegateto theU.S. House of Representatives. The city's voters choose threepresidential electorsin accordance with theTwenty-third Amendment.

Washington, D.C. anchors the southern end of theNortheast megalopolis. As the seat of theU.S. federal government, the city is an importantworld political capital.^[13]The city hosts the buildings that house federal government headquarters, including theWhite House, the Capitol, theSupreme Court Building, andmultiple federal departments and agencies. The city is home to many nationalmonuments and museums, located most prominently on or around theNational Mall, including theJefferson Memorial, theLincoln Memorial, and theWashington Monument. It hosts177 foreign embassiesand serves as the headquarters for theWorld Bank, theInternational Monetary Fund, theOrganization of American States, and other international organizations. Home to many of the nation's largest industry associations, non-profit organizations, andthink tanks, D.C. is known as alobbyinghub, withK Streetas the industry center.^[14]The city had 20.7 million domestic visitors^[15]and 1.2 million international visitors, ranking seventh among U.S. cities as of 2022.^[16]

Various tribes of theAlgonquian-speakingPiscataway people, also known as the Conoy, inhabited the lands around thePotomac Riverand present-day Washington, D.C., when Europeans first arrived and colonized the region in the early 17th century. TheNacotchtank, also called the Nacostines byCatholic missionaries, maintained settlements around theAnacostia Riverin present-day Washington, D.C. Conflicts withEuropean colonistsand neighboring tribes ultimately displaced the Piscataway people, some of whom established a new settlement in 1699 nearPoint of Rocks, Maryland.^[17]

Nine cities served as capitalsto theContinental Congressand under theArticles of Confederation.New York Citywas the first capital upon the adoption of theConstitution, succeeded byPhiladelphia, which was capital from 1790 to 1800.^[18]

On October 6, 1783, after the capital was forced by thePennsylvania Mutiny of 1783to move to Princeton, Congress resolved to consider a new location for it.^[19]The following day,Elbridge Gerryof Massachusetts moved "that buildings for the use of Congress be erected on the banks of theDelawarenearTrenton, or of thePotomac, nearGeorgetown, provided a suitable district can be procured on one of the rivers as aforesaid, for a federal town".^[20]

InFederalist No. 43, published January 23, 1788,James Madisonargued that the newfederal governmentwould need authority over a national capital to provide for its own maintenance and safety.^[21]The Pennsylvania Mutiny of 1783 emphasized the need for the national government not to rely on any state for its own security.^[22]

Article One, Section Eightof the Constitution permits the establishment of a "District (not exceeding ten miles square) as may, by cession of particular states, and the acceptance of Congress, become the seat of the government of the United States".^[23]However, the constitution does not specify a location for the capital. In theCompromise of 1790, Madison,Alexander Hamilton, andThomas Jeffersonagreed that the federal government would pay each state's remainingRevolutionary Wardebts in exchange for establishing the new national capital in theSouthern United States.^[24][a]

On July 9, 1790, Congress passed theResidence Act, which approved the creation of a national capital on thePotomac River. Under the Residence Act, the exact location was to be selected by PresidentGeorge Washington, who signed the bill into law on July 16, 1790. Formed from land donated by Maryland and Virginia, the initial shape of the federal district was a square measuring 10 miles (16 km) on each side and totaling 100 square miles (259 km²).^[25][b]

Two pre-existing settlements were included in the territory, the port ofGeorgetown, founded in 1751,^[26]and theportcity ofAlexandria, Virginia, founded in 1749.^[27]In 1791 and 1792, a team led byAndrew Ellicott, including Ellicott's brothersJosephandBenjaminand African AmericanastronomerBenjamin Banneker, whose parents had been enslaved, surveyed the borders of the federal district and placedboundary stonesat every mile point; many of these stones are still standing.^[28][29]Both Maryland and Virginia wereslave states, andslavery existedin the District from its founding. The building of Washington likely relied in significant part on slave labor, and slave receipts have been found for the White House, Capitol Building, and establishment of Georgetown University. The city became an importantslave marketand a center of the nation'sinternal slave trade.^[30][31]

After its survey, the newfederal citywas constructed on the north bank of the Potomac River, to the east of Georgetown centered onCapitol Hill. On September 9, 1791, three commissioners overseeing the capital's construction named the city in honor of President Washington. The same day, the federal district was named Columbia, a feminine form ofColumbus, which wasa poetic name for the United Statescommonly used at that time.^[32][33]Congress held its first session there on November 17, 1800.^[34]

Congress passed theDistrict of Columbia Organic Act of 1801, which officially organized the district and placed the entire territory under theexclusive controlof the federal government. The area within the district was organized into two counties, theCounty of Washingtonto the east and north of the Potomac and theCounty of Alexandriato the west and south.^[35]After the Act's passage, citizens in the district were no longer considered residents of Maryland or Virginia, which ended their representation in Congress.^[36]

On August 24, 1814, during theWar of 1812,Britishforces invaded and occupied the city after defeating an American forceat Bladensburg. In retaliation for acts of destruction by American troops inthe Canadas, the British set fire to government buildings in the city, gutting theUnited States Capitol, theTreasury Building, and theWhite Housein what became known as theburning of Washington. However, a storm forced the British to evacuate the city after just 24 hours.^[37]Most government buildings were repaired quickly, but the Capitol, which was largely under construction at the time, would not be completed in its current form until 1868.^[38]

In the 1830s, the district's southern territory ofAlexandriadeclined economically, due in part to its neglect by Congress.^[39]Alexandria was a major market in thedomestic slave tradeand pro-slavery residents feared thatabolitionistsin Congress would endslavery in the district. Alexandria's citizens petitioned Virginia to retake the land it had donated to form the district, a process known asretrocession.^[40]

TheVirginia General Assemblyvoted in February 1846, to accept the return of Alexandria. On July 9, 1846, Congress went further, agreeing to return all territory that Virginia had ceded to the district during its formation. This left the district's area consisting only of the portion originally donated by Maryland.^[39]Confirming the fears of pro-slavery Alexandrians, theCompromise of 1850outlawed the slave trade in the district, although not slavery itself.^[41]

The outbreak of theAmerican Civil Warin 1861 led to the expansion of the federal government and notable growth in the city's population, including a large influx of freed slaves.^[42]PresidentAbraham Lincolnsigned theCompensated Emancipation Actin 1862, which ended slavery in the district, freeing about 3,100 slaves in the district nine months before theEmancipation Proclamation.^[43]In 1868, Congress granted the district'sAfrican Americanmale residents the right to vote in municipal elections.^[42]

By 1870, the district's population had grown 75% in a decade to nearly 132,000 people,^[44]yet the city still lacked paved roads and basic sanitation. Some members of Congress suggested moving the capital farther west, but PresidentUlysses S. Grantrefused to consider the proposal.^[45]

In theOrganic Act of 1871, Congress repealed the individual charters of the cities of Washington andGeorgetown, abolishedWashington County, and created a new territorial government for the whole District of Columbia.^[46]These steps made "the city of Washington...legally indistinguishable from the District of Columbia."^[47]

In 1873, President Grant appointedAlexander Robey Shepherdas Governor of the District of Columbia. Shepherd authorized large projects that modernized the city but bankrupted its government. In 1874, Congress replaced the territorial government with an appointed three-member board of commissioners.^[48]

In 1888, the city'sfirst motorized streetcarsbegan service. Their introduction generated growth in areas of the district beyond the City of Washington's original boundaries, leading to an expansion of the district over the next few decades.^[49]Georgetown's street grid and other administrative details were formally merged with those of the City of Washington in 1895.^[50]However, the city had poor housing and strained public works, leading it to become the first city in the nation to undergourban renewalprojects as part of theCity Beautiful movementin the early 20th century.^[51]

TheCity Beautifulmovement built heavily upon the already-implementedL'Enfant Plan, with the newMcMillan Planleading urban development in the city throughout the movement. Much of the oldVictorianMallwas replaced with modernNeoclassicalandBeaux-Arts architecture; these designs are still prevalent in the city's governmental buildings today.

Increased federal spending under theNew Dealin the 1930s led to the construction of new government buildings, memorials, and museums in the district,^[52]though the chairman of the House Subcommittee on District Appropriations,Ross A. CollinsofMississippi, justified cuts to funds for welfare and education for local residents by saying that "my constituents wouldn't stand for spending money on niggers."^[53]

World War IIled to an expansion of federal employees in the city;^[54]by 1950, the district's population reached its peak of 802,178 residents.^[44]

TheTwenty-third Amendment to the United States Constitutionwas ratified in 1961, granting the district three votes in theElectoral Collegefor the election of president and vice president, but still not affording the city's residents representation in Congress.^[55]

After theassassination of civil rights leader Martin Luther King Jr.on April 4, 1968,riots broke out in the city, primarily in the U Street, 14th Street, 7th Street, and H Street corridors, which were predominantly black residential and commercial areas. The riots raged for three days until more than 13,600 federal troops andWashington, D.C., Army National Guardsmenstopped the violence. Many stores and other buildings were burned, and rebuilding from the riots was not completed until the late 1990s.^[56]

In 1973, Congress enacted theDistrict of Columbia Home Rule Actproviding for an elected mayor and 13-member council for the district.^[57]In 1975,Walter Washingtonbecame the district's first elected and first black mayor.^[58]

Since the 1980s, theD.C. statehood movementhas grown in prominence. In 2016, areferendum on D.C. statehoodresulted in an 85% support among Washington, D.C., voters for it to become the nation's51st state. In March 2017, the city's congressional delegateEleanor Holmes Nortonintroduced a bill for statehood. Reintroduced in 2019 and 2021 as theWashington, D.C., Admission Act, theU.S. House of Representativespassed it in April 2021.^{[citation needed]}After not progressing in the Senate, the statehood bill was introduced again in January 2023.^[59]

Washington, D.C., is located in theMid-Atlantic regionof theU.S. East Coast. The city has a total area of 68.34 square miles (177 km²), of which 61.05 square miles (158.1 km²) is land and 7.29 square miles (18.9 km²) (10.67%) is water.^[60]The district is bordered byMontgomery County, Maryland, to the northwest;Prince George's County, Maryland, to the east;Arlington County, Virginia, to the west; andAlexandria, Virginia, to the south.

The south bank of thePotomac Riverforms the district's border with Virginia and has two major tributaries, theAnacostia RiverandRock Creek.^[61]Tiber Creek, a natural watercourse that once passed through theNational Mall, was fully enclosed underground during the 1870s.^[62]The creek also formed a portion of the now-filledWashington City Canal, which allowed passage through the city to the Anacostia River from 1815 until the 1850s.^[63]TheChesapeake and Ohio Canalstarts inGeorgetownand was used during the 19th century to bypass theLittle Fallsof the Potomac River, located at the northwest edge of the city at theAtlantic Seaboard fall line.^[64]

The highest natural elevation in the district is 409 feet (125 m)above sea levelatFort Reno Parkin uppernorthwest Washington, D.C.^[65]The lowest point is sea level at the Potomac River.^[66]The geographic center of Washington is near the intersection of 4th and L streets NW.^[67][68][69]

The district has 7,464 acres (30.21 km²) of parkland, about 19% of the city's total area, the second-highest among high-density U.S. cities afterPhiladelphia.^[70]The city's sizable parkland was a factor in the city being ranked as third in the nation for park access and quality in the 2018 ParkScore ranking of the park systems of the nation's 100 most populous cities, according toTrust for Public Land, a non-profit organization.^[71]

TheNational Park Servicemanages most of the 9,122 acres (36.92 km²) of city land owned by the U.S. government.^[72]Rock Creek Park is a 1,754-acre (7.10 km²) urban forest in Northwest Washington, which extends 9.3 miles (15.0 km) through a stream valley that bisects the city. Established in 1890, it is the country's fourth-oldest national park and is home to a variety of plant and animal species, including raccoon, deer, owls, and coyotes.^[73]Other National Park Service properties include theChesapeake and Ohio Canal National Historical Park, theNational Mall and Memorial Parks,Theodore Roosevelt Island,Columbia Island,Fort Dupont Park,Meridian Hill Park,Kenilworth Park and Aquatic Gardens, andAnacostia Park.^[74]TheDistrict of Columbia Department of Parks and Recreationmaintains the city's 900 acres (3.6 km²) of athletic fields and playgrounds, 40 swimming pools, and 68 recreation centers.^[75]TheU.S. Department of Agricultureoperates the 446-acre (1.80 km²)United States National ArboretuminNortheast Washington, D.C.^[76]

Washington's climate ishumid subtropical(Köppen:Cfa), oroceanic(Trewartha:DoborderingCfdowntown).^[77][78]Winters are cool to cold with some snow of varying intensity, while summers are hot and humid. The district is in planthardiness zone8a near downtown, and zone 7b elsewhere in the city.^[79][80]

Summers are hot and humid with a July daily average of 79.8 °F (26.6 °C) and average daily relative humidity around 66%, which can cause moderate personal discomfort. Heat indices regularly approach 100 °F (38 °C) at the height of summer.^[81]The combination of heat and humidity in the summer brings very frequent thunderstorms, some of which occasionally produce tornadoes in the area.^[82]

Blizzards affect Washington once every four to six years on average. The most violent storms, known asnor'easters, often impact large regions of theEast Coast.^[83]FromJanuary 27 to 28, 1922, the city officially received 28 inches (71 cm) of snowfall, the largest snowstorm since official measurements began in 1885.^[84]According to notes kept at the time, the city received between 30 and 36 inches (76 and 91 cm) from a snowstorm in January 1772.^[85]

Hurricanes or their remnants occasionally impact the area in late summer and early fall. However, they usually are weak by the time they reach Washington, partly due to the city's inland location.^[86]Flooding of thePotomac River, however, caused by a combination of high tide, storm surge, and runoff, has been known to cause extensive property damage in theGeorgetownneighborhood of the city.^[87]Precipitation occurs throughout the year.^[88]

The highest recorded temperature was 106 °F (41 °C) on August 6, 1918, and on July 20, 1930.^[89]The lowest recorded temperature was −15 °F (−26 °C) onFebruary 11, 1899, right before theGreat Blizzard of 1899.^[83]During a typical year, the city averages about 37 days at or above 90 °F (32 °C) and 64 nights at or below the freezing mark (32 °F or 0 °C).^[90]On average, the first day with a minimum at or below freezing is November 18 and the last day is March 27.^[91][92]

Washington, D.C., was aplanned city, and many of the city'sstreet gridswere developed in that initial plan. In 1791, PresidentGeorge WashingtoncommissionedPierre Charles L'Enfant, a French-born military engineer and artist, to design the new capital. He enlisted the help of Isaac Roberdeau,Étienne Sulpice Halletand Scottish surveyorAlexander Ralstonto help lay out the city plan.^[97]TheL'Enfant Planfeatured broad streets and avenues radiating out from rectangles, providing room for open space and landscaping.^[98]

L'Enfant was also provided a roll of maps byThomas Jeffersondepicting Frankfurt, Amsterdam, Strasbourg, Paris, Orleans, Bordeaux, Lyon, Marseille, Turin, and Milan.^[99]L'Enfant's design also envisioned a garden-lined grand avenue about 1 mile (1.6 km) long and 400 feet (120 m) wide in an area that is now theNational Mallinspired by the grounds atVersaillesandTuileriesGardens.^[100]In March 1792, President Washington dismissed L'Enfant due to conflicts with the three commissioners appointed to supervise the capital's construction.Andrew Ellicott, who worked with L'Enfant in surveying the city, was then tasked with completing its design. Though Ellicott revised the original L'Enfant plans, including changing some street patterns, L'Enfant is still credited with the city's overall design.^[101]

By the early 20th century, however, L'Enfant's vision of a grand national capital was marred by slums and randomly placed buildings in the city, including a railroad station on the National Mall. Congress formed a special committee charged with beautifying Washington's ceremonial core.^[51]What became known as theMcMillan Planwas finalized in 1901 and included relandscaping the Capitol grounds and the National Mall, clearing slums, and establishing a new citywide park system. The plan is thought to have largely preserved L'Enfant's intended design for the city.^[98]

By law, the city's skyline is low and sprawling. The federalHeight of Buildings Act of 1910prohibits buildings with height exceeding the width of the adjacent street plus 20 feet (6.1 m).^[102]Despite popular belief, no law has ever limited buildings to the height of the United States Capitol or the 555-foot (169 m)Washington Monument,^[69]which remains the district's tallest structure. City leaders have cited the height restriction as a primary reason that the district has limited affordable housing and its metro area has suburban sprawl and traffic problems.^[102]Washington, D.C., still has a relatively high homelessness rate, despite its high living standard compared to many American cities.^[103]

Washington, D.C., is divided intofour quadrantsof unequal area:Northwest (NW),Northeast (NE),Southeast (SE), andSouthwest (SW). The axes bounding the quadrants radiate from the U.S. Capitol.^[104]All road names include the quadrant abbreviation to indicate their location. House numbers generally correspond with the number of blocks away from the Capitol. Most streets are set out in a grid pattern with east–west streets named with letters (e.g., C Street SW), north–south streets with numbers (e.g., 4th Street NW), and diagonal avenues, many of which arenamed after states.^[104]

The City of Washington was bordered on the north by Boundary Street (renamedFlorida Avenuein 1890);Rock Creekto the west, and theAnacostia Riverto the east.^[49][98]Washington, D.C.'s street grid was extended, where possible, throughout the district starting in 1888.^[105]Georgetown's streetswere renamed in 1895.^[50]Some streets are particularly noteworthy, includingPennsylvania Avenue, which connects theWhite Houseto the Capitol; and K Street, which houses the offices of many lobbying groups.^[106]Constitution AvenueandIndependence Avenue, located on the north and south sides of the National Mall, respectively, are home to many of Washington's iconic museums, including manySmithsonian Institutionbuildings and theNational Archives Building. Washington hosts 177foreign embassies; these maintain nearly 300 buildings and more than 1,600 residential properties, many of which are on a section ofMassachusetts Avenueinformally known asEmbassy Row.^[107]

The architecture of Washington, D.C., varies greatly and is generally popular among tourists and locals. In 2007, six of the top ten buildings in theAmerican Institute of Architects' ranking ofAmerica's Favorite Architecturewere in the city:^[108]theWhite House,Washington National Cathedral, theJefferson Memorial, theUnited States Capitol, theLincoln Memorial, and theVietnam Veterans Memorial. Theneoclassical,Georgian,Gothic, andModernstyles are reflected among these six structures and many other prominent edifices in the city.^{[citation needed]}

Many of the government buildings, monuments, and museums along theNational Malland surrounding areas are heavily inspired byclassicalRomanandGreekarchitecture. The designs of the White House, the U.S. Capitol,Supreme Court Building,Washington Monument,National Gallery of Art, Lincoln Memorial, and Jefferson Memorial are all heavily drawn from these classical architectural movements and feature large pediments, domes, columns in classical order, and heavy stone walls. Notable exceptions to the city's classical-style architecture include buildings constructed in theFrench Second Empirestyle, including theEisenhower Executive Office Building, and the modernistWatergate complex.^[109]TheThomas Jefferson Building, the mainLibrary of Congressbuilding, and the historicWillard Hotelare built inBeaux-Arts style, popular throughout the world in the late nineteenth and early twentieth centuries.^[110][111]Meridian Hill Parkcontains acascading waterfallwithItalian Renaissance-style architecture.^[112]

Modern,Postmodern,contemporary, and other non-classical architectural styles are also seen in the city. TheNational Museum of African American History and Culturedeeply contrasts the stone-based neoclassical buildings on theNational Mallwith a design that combines modern engineering with heavy inspiration fromAfrican art.^[113]The interior of theWashington Metrostations and theHirshhorn Museum and Sculpture Gardenare designed with strong influence from the 20th-centuryBrutalismmovement.^[114]TheSmithsonian Institution Buildingis built ofSeneca redsandstonein theNorman Revivalstyle.^[115]TheOld Post Officebuilding, located onPennsylvania Avenueand completed in 1899, was the first building in the city to have asteel framestructure and the first to use electrical wiring in its design.^[116]

Notablecontemporaryresidential buildings, restaurants, shops, and office buildings in the city includethe Wharfon theSouthwest Waterfront,Navy Yardalong theAnacostia River, andCityCenterDCinDowntown. The Wharf has seen the construction of several high-rise office and residential buildings overlooking thePotomac River. Additionally, restaurants, bars, and shops have been opened at street level. Many of these buildings have a modern glass exterior and heavy curvature.^[117][118]CityCenterDC is home to Palmer Alley, a pedestrian-only walkway, and houses several apartment buildings, restaurants, and luxury-brand storefronts with streamlined glass and metal facades.^[119]

Outside Downtown D.C., architectural styles are more varied. Historic buildings are designed primarily in theQueen Anne,Châteauesque,Richardsonian Romanesque,Georgian Revival,Beaux-Arts, and a variety ofVictorianstyles.^{[citation needed]}Rowhouses are prominent in areas developed after theCivil Warand typically followFederaland lateVictoriandesigns.^[120]Georgetown'sOld Stone House, built in 1765, is the oldest-standing building in the city.^[121]Founded in 1789,Georgetown Universityfeatures a mix of Romanesque andGothic Revival architecture.^[109]TheRonald Reagan Buildingis the largest building in the district with a total area of about 3.1 million square feet (288,000 m²).^[122]Washington Union Stationis designed in a combination of architectural styles. Its Great Hall has elaborate gold leaf designs along the ceilings and the hall includes several decorative classical-style statues.^[123]

Article One, Section Eight of the United States Constitutiongrants theUnited States Congress"exclusive jurisdiction" over the city. The district did not have an elected local government until the passage of the1973 Home Rule Act. The Act devolved certain Congressional powers to anelected mayorand the thirteen-memberCouncil of the District of Columbia. However, Congress retains the right to review and overturn laws created by the council and intervene in local affairs.^[269]Washington, D.C., isoverwhelmingly Democratic,having votedfor the Democratic presidential candidate solidly since it was granted electoral votesin 1964.^[270]

The phrase is used as a title for a number of political columns and news items by publications likeThe Washington Times.^[276]

The mayor and council set local taxes and a budget, which Congress must approve. TheGovernment Accountability Officeand other analysts have estimated that the city's high percentage of tax-exempt property and the Congressional prohibition of commuter taxes create a structural deficit in the district's local budget of anywhere between $470 million and over $1 billion per year. Congress typically provides additional grants for federal programs such asMedicaidand the operation of thelocal justice system; however, analysts claim that the payments do not fully resolve the imbalance.^[277][278]

The city's local government, particularly during the mayoralty ofMarion Barry, has been criticized for mismanagement and waste.^[279]During his administration in 1989,Washington Monthlymagazine labeled the district "the worst city government in America".^[280]In 1995, at the start of Barry's fourth term, Congress created theDistrict of Columbia Financial Control Boardto oversee all municipal spending.^[281]MayorAnthony Williamswon election in 1998 and oversaw a period ofurban renewaland budget surpluses.^{[citation needed]}

Trump's 2019 Independence Day event, "A Salute to America", cost six times more than Independence Day events in past years.^[283]

Washington, D.C. is not a state and therefore has no federal voting representation inCongress. The city's residents elect anon-voting delegateto theHouse of Representatives(D.C. at-large), who may sit on committees, participate in debate, and introduce legislation, but cannot vote on theHouse floor. The district has no official representation in theUnited States Senate. Neither chamber seats the district's elected"shadow" representative or senators. Unlike residents ofU.S. territoriessuch asPuerto RicoorGuam, which also have non-voting delegates, D.C. residents are subject to all federal taxes.^[284]In the financial year 2012, D.C. residents and businesses paid $20.7 billion in federal taxes, more than the taxes collected from 19 states and the highestfederal taxes per capita.^[285]

Opponents to federal voting rights for Washington, D.C., propose that theFounding Fathersnever intended for district residents to have a vote in Congress since the Constitution makes clear that representation must come from the states. Those opposed to making District of Columbia a state claim such a move would destroy the notion of a separate national capital and that statehood would unfairly grant Senate representation to a single city.^[289]

The city passed a law that requires shelter to be provided to everyone in need when the temperature drops below freezing.^[290]Since D.C. does not have enough shelter units available, every winter it books hotel rooms in the suburbs with an average cost around $100 for a night. According to the D.C.
