Biden escorted into chamber by 1st Black House sergeant at arms
As Biden enters the House chamber to deliver his joint address, the person who is escorting him in and announced his arrival is a newly minted House sergeant at arms, Major General William Walker.
Walker is the first Black man to serve as the House sergeant at arms and is now the top security official of the chamber. House Speaker Nancy Pelosi administered the oath of office to Walker during a pro forma session in the House on Monday.
Walker, the former commander of the D.C. National Guard, is the 38th sergeant-at-arms for the House and it's now his responsibility to keep the chamber and its members safe.
His appointment came in the wake of the Jan. 6 riot attack at the U.S. Capitol. Pelosi noted in a March statement at the time of his appointment, that "his experience will be an important asset to the House, particularly in light of the January 6 insurrection."
