The core computer operations are in that building, and the staff manages Internet and intranet connections to offices of senators both in the Capitol complex and back in their home states.

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.

[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.

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.

[10] On the same day, Mitch McConnell, the outgoing Senate Majority Leader, asked for and received Stenger's resignation, effective immediately.

[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.
