The Mount Vernon Triangle Historic District is a historic district in the Mount Vernon Triangle neighborhood of Washington, D.C., consisting of 22 contributing residential, commercial, and industrial buildings, and one known archaeological site. The area was once a working class neighborhood for mostly German immigrants and home to semi-industrial enterprises such as a dairy and an automobile repair shop. The Northern Liberty Market that once stood on the corner of 5th Street and K Street NW played a large role in spurring development in the surrounding area as did the streetcars on Massachusetts Avenue and New York Avenue. The historic district was added to the District of Columbia Inventory of Historic Sites in 2005 and the National Register of Historic Places in 2006. The 22 buildings in the district were constructed between 1869 and 1946. Two of the buildings included in the historic designation process, 470 and 472 K Street NW, collapsed in 2014. Many of the buildings in the district have undergone a restoration process. Prather's Alley, which was once lined with dwellings, stables, and industrial businesses, is being redeveloped into a place for community residents to gather.

The District of Columbia's at-large congressional district is a congressional district based entirely of the District of Columbia. According to the U.S. Constitution, only states may be represented in the Congress of the United States. The District of Columbia is not a U.S. state and therefore has no voting representation. Instead, constituents in the district elect a non-voting delegate to the U.S. House of Representatives. Despite lacking full voting privileges on the floor of the House of Representatives, delegates are voting members in U.S. Congressional committees and they lobby their congressional colleagues regarding the District's interests. While the office was initially created during the Reconstruction Era by the Radical Republicans, Norton P. Chipman (R) briefly held the seat for less than two terms before the office was eliminated completely. The District of Columbia Delegate Act Pub.L. 91–405, 84 Stat. 845-2 of 1970 authorized voters in the District of Columbia to elect one non-voting delegate to represent them in the United States House of Representatives. The act was approved by Congress on September 22, 1970 and subsequently signed into law by President Richard Nixon. Democrat Walter E. Fauntroy was elected as the district's delegate to Congress in a special election on March 23, 1971, receiving 58 percent of the 116,635 votes cast.Since 1993, when the House of Representatives has been under Democratic control, delegates, including the District of Columbia's delegate, have been allowed to cast non-binding floor votes when the House of Representatives was operating in the Committee of the Whole.The district is currently represented by Democrat Eleanor Holmes Norton.
