those sessions. When the sessions became public, the Doorkeeper became in charge of security in the chamber and the gallery. In 1798, the title of Sergeant at Arms was appended to the Office of the Doorkeeper after Mathers was authorized to compel former senator William Blount to return to Philadelphia and face an impeachment trial. Shortly afterwards the Sergeant at Arms was given additional powers to compel absent senators to attend sessions, which has typically been used to summon members when ending filibusters in the United States Senate. In 1829, the sergeant at arms began supervising Senate pages, after the appointment of the first page. In 1854, the Senate's first postmaster and post office initially operated out of the sergeant at arms's office. In 1867, the sergeant at arms was given regulation-making power to maintain, protect, and police the Capitol and the Senate Office Buildings. The sergeant at arms's role was also expanded to include serving as the Senate's wagon master and keeper of the Senate stables. In 1913, when the Senate purchased its first automobile for use by the vice president, the sergeant at arms also became responsible for leasing, maintenance, traffic control, and parking of all cars around the Capitol. In 1897, James D. Preston, a doorkeeper in the Senate Press Gallery working under the sergeant at arms, began helping the reporters with collecting legislative bills, gathering information, and organizing interviews with senators. Preston was eventually installed as the first superintendent of the Senate Press Gallery. As new forms of media emerged in the 1930s and 1940s, this superintendent role expanded in parallel. Martha S. Pope was the first woman to serve as Sergeant at Arms for either chamber, being elected by the Senate for the 102nd and 103rd Congresses. On January 7, 2021, Senate Democratic Leader Chuck Schumer announced that he would fire the incumbent Sergeant at Arms, Michael C. Stenger, if he was not fired or did not resign prior to Schumer's being appointed as Senate Majority Leader. This announcement was made the day after the Capitol Building was attacked by a violent group of supporters of President Donald Trump. The attack resulted in the death of at least 5 people and extensive damage of more than $2 million of the building itself. On the same day, Mitch McConnell, the outgoing Senate Majority Leader, asked for and received Stenger's resignation, effective immediately. Deputy Sergeant at Arms
