One of the longest serving House Sergeant-at-Arms and former Secret Service agent Bill Livingood is retiring after five decades of public service. Politico reports:

House Sergeant-at-Arms Wilson “Bill” Livingood, who led the chamber through some of the greatest security crises in the history of the U.S. Capitol, is retiring after nearly 17 years in the post.

The affable and low-key Livingood served with the Secret Service for 33 years before being appointed sergeant-at-arms in January 1995, standing as the top security officer on the House side during the tense moments of Sept. 11, the anthrax scares and the 1998 shootings of two U.S. Capitol police officers.
