Capitol police officer who protected Congress on Jan. 6 launches bid to join it

Retired Capitol Police officer Harry Dunn announced Friday that he was joining the busy Democratic primary in the race to succeed retiring Rep. John Sarbanes, a declaration that came one day ahead of the third anniversary of the Jan. 6 attack.

"I swore an oath to protect our constitution, to protect our democracy," Dunn says in his launch video, which features a recreation of the riot.

The candidate, who is Black, continues by describing how he "protect[ed] some members of Congress who I knew were bigots, who helped fan the flames that started all of this. I put country above self." He goes on, "Some of the same people who stood behind us when we protected them went back on the floor of Congress and stood behind Trump."
