The Washington Depot or New Jersey Avenue Station was a train station located in Northwest Washington, D.C., a block north of the Capitol. The train station was also called the B&O Depot as it was served by the Baltimore & Ohio Railroad. It operated from April 1851 until October 26, 1907, when Union Station commenced operation. During the American Civil War, the New Jersey Avenue Station was the major embarkation site for hundreds of thousands of Union troops. President Abraham Lincoln arrived there to be sworn in as President in 1861. It was from that station that his body along with his son "Willie" Lincoln began its long journey to his final resting place in Illinois after he was assassinated on April 14, 1865.

The Capitol Christmas Tree (formerly the Capitol Holiday Tree) is the decorated tree that is erected annually on the West Front Lawn of the United States Capitol, in Washington, D.C., to celebrate the Christmas holiday season. The selection, installation, and decoration of the tree are all overseen by the Superintendent of the Capitol Grounds of the Architect of the Capitol (AOC). The tree is traditionally lit by the Speaker of the United States House of Representatives, joined by a essay contest winner during a ceremony at the beginning of December, and remains lit each night through New Year's Day.

Capitol Hill, in addition to being a metonym for the United States Congress, is the largest historic residential neighborhood in Washington, D.C., stretching easterly in front of the United States Capitol along wide avenues. It is one of the oldest residential neighborhoods in Washington, D.C., and, with roughly 35,000 people in just under 2 square miles (5 km2), it is also one of the most densely populated.As a geographic feature, Capitol Hill rises near the center of the District of Columbia and extends eastward. Pierre (Peter) Charles L'Enfant, as he began to develop his plan for the new federal capital city in 1791, chose to locate the "Congress House" (the Capitol building) on the crest of the hill at a site that he characterized as a "pedestal waiting for a monument." The Capitol building has been the home of the Congress of the United States and the workplace of many residents of the Capitol Hill neighborhood since 1800. The Capitol Hill neighborhood today straddles two quadrants of the city, Southeast and Northeast. A large portion of the neighborhood is now designated as the Capitol Hill Historic District. The name Capitol Hill is often used to refer to both the historic district and to the larger neighborhood around it. To the east of Capitol Hill lies the Anacostia River, to the north is the H Street corridor, to the south are the Southeast/Southwest Freeway and the Washington Navy Yard, and to the west are the National Mall and the city's central business district. The Capitol building is surrounded by the Capitol Hill Historic District, which is listed on the National Register of Historic Places (NRHP). The Capitol Hill Historic District was expanded in 2015 to the north to include the blocks bordered by 2nd Street, F Street, 4th Street, and just south of H Street, NE, collectively known as the Swampoodle Addition.

On January 6, 2021, Ashli Babbitt was fatally shot during an attack on the United States Capitol. She was part of a crowd of supporters of U.S. President Donald Trump who breached the United States Capitol building seeking to overturn his defeat in the 2020 presidential election. Babbitt attempted to climb through a shattered window beside a barricaded door into the Speaker's Lobby, and was subsequently shot in the left shoulder by a United States Capitol Police (USCP) officer. After a USCP emergency response team administered aid, Babbitt was transported to Washington Hospital Center, where she later died. The USCP deemed the shooting was "lawful and within Department policy" and "potentially saved Members (of Congress) and staff from serious injury and possible death".

The United States Senate is the upper chamber of the United States Congress, with the House of Representatives being the lower chamber. Together they compose the national bicameral legislature of the United States. The composition and powers of the Senate are established by Article One of the United States Constitution. The Senate is composed of senators, each of whom represents a single state in its entirety. Each of the 50 states is equally represented by two senators who serve staggered terms of six years, for a total of 100 senators. From 1789 to 1913, senators were appointed by legislatures of the states they represented. They have been elected by popular vote since the 1913 ratification of the Seventeenth Amendment. As the upper chamber of Congress, the Senate has several powers of advice and consent which are unique to it. These include the approval of treaties, and the confirmation of Cabinet secretaries, federal judges (including Federal Supreme Court justices), flag officers, regulatory officials, ambassadors, other federal executive officials and federal uniformed officers. If no candidate receives a majority of electors for vice president, the duty falls to the Senate to elect one of the top two recipients of electors for that office. The Senate conducts trials of those impeached by the House. The Senate has typically been considered both a more deliberative and prestigious body than the House of Representatives due to its longer terms, smaller size, and statewide constituencies, which historically led to a more collegial and less partisan atmosphere.The Senate chamber is located in the north wing of the Capitol Building in Washington, D.C. The vice president of the United States serves as presiding officer and president of the Senate by virtue of that office, despite not being a senator, and has a vote only if the Senate is equally divided. In the vice president's absence, the president pro tempore, who is traditionally the senior member of the party holding a majority of seats, presides over the Senate. In the early 1920s, the practice of majority and minority parties electing their floor leaders began. The Senate's legislative and executive business is managed and scheduled by the Senate majority leader.
