Speaker Nancy Pelosi announced Friday that Maj. Gen. William Walker will serve as the new House sergeant-at-arms and said his military background would help make the Capitol more secure following the Jan. 6 attack by hundreds of angry protesters.

“His experience will be an important asset to the House, particularly in light of the Jan. 6 insurrection,” said Pelosi, a California Democrat. “It is essential that we work to strengthen our institution and keep our Capitol community, and all who visit, safe.”
