The office of the sergeant at arms of the Senate has between 800 and 900 staff,^{[clarification needed]} of the approximately 4,300 working for the Senate overall.

The Office of the Doorkeeper was created on April 7, 1789, during the 1st United States Congress to address the Senate's inability to keep a majority of senators in the Capitol long enough to meet quorum and conduct business. The Senate had first convened on March 4, 1789, but only met quorum for the first time on April 6, 1789, one day before the appointment of the first doorkeeper, James C. Mathers. Because Senate sessions were held in private for the first six years, the doorkeeper was in charge of access to those sessions. When the sessions became public, the doorkeeper became in charge of security in the chamber and the gallery.^[7]

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.^[7]

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.^[7]

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.

Stenger, if he was not fired or did not resign prior to Schumer's being appointed as Senate Majority Leader.^[9] 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.^[10] On the same day, Mitch McConnell, the outgoing Senate Majority Leader, asked for and received Stenger's resignation, effective immediately.^[11] Deputy Sergeant at Arms Jennifer Hemingway was announced by McConnell as the acting sergeant-at-arms.^[12] On January 20, 2021, Eugene Goodman was announced as the acting deputy sergeant at arms of the United States Senate when stepping out onto the inauguration platform ahead of Kamala Harris.^[13][14]
