The man accused of shooting at Secret Service agents on the National Mall in Washington on Monday has been identified as Michael Marx, 45, of Texas, according to two people familiar with the matter.

Shots rang out just south of the White House on Monday afternoon in an exchange of gunfire that also grazed a young bystander in an area packed with pedestrians, officials said.

The suspect, who was shot by Secret Service agents, was taken to a hospital with multiple gunshot wounds. Mr. Marx has yet to face charges. No law enforcement officials were injured, and there was no immediate sign that the man was targeting anyone in the executive complex, according to Chris McDonald, a congressional affairs official with the Secret Service.

The episode began around 3:30 p.m. near the intersection of 15th Street Southwest and Independence Avenue, when agents walked up to a man “who appeared to be carrying a weapon,” Mr. McDonald wrote in an email to Congress on Monday.

Matt Quinn, the deputy director of the Secret Service, told reporters that as the agents approached, Mr. Marx ran off and shot at them. The agents fired back and apprehended him, Mr. Quinn said. Shortly before the commotion rang out, Vice President JD Vance passed the scene of the shooting in his motorcade, but there was no clear indication that the suspect was targeting the vice president, Mr. Quinn added.

A firearm was recovered at the scene, and a 15-year-old boy hit by gunfire was treated for a non-life-threatening wound, officials said.

The shooting took place a little more than a week after a gunman stormed a security checkpoint at the White House Correspondents’ Association dinner and shot a Secret Service agent in an attack that officials said was targeting administration officials.
