Secret Service agents exchanged gunfire with a “suspicious individual” near the Washington Monument on Monday afternoon, shortly before Vice President JD Vance’s motorcade traveled through the area, the agency’s deputy director said—nine days after a shooting at the White House Correspondents’ Dinner involving a man prosecutors say was targeting members of the Trump administration.

One juvenile bystander was hit during the exchange of gunfire, authorities said.

Plainclothes officers that patrol outside the White House identified a “suspicious individual” at the Washington Monument around 3:30 p.m. EDT, the agency’s deputy director Matt Quinn said at a press conference.

The suspect had a “visual print” of a firearm, Quinn said, and fled after uniformed Secret Service officers approached, Quinn said.

He said the suspect opened fire at the agents, who returned fire—hitting the suspect, who has since been hospitalized.
