For the second time in as many weeks, a U.S. Secret Service agent fired a gun at an armed suspect in Washington D.C., less than a mile from the White House.

The US Secret Service says its officers shot an armed man Monday afternoon near the Washington Monument after he fired at agents and wounded a juvenile bystander.

The man fled on foot after being approached by the officers, drew his weapon and opened fire, Quinn said.

Authorities arrested a man Saturday at Trump Doral National Golf Club in Miami after the individual became unruly and got physical with a Secret Service agent, a federal official said.
