WASHINGTON, D.C. — Michael Marx, 45, allegedly fired a handgun at U.S. Secret Service officers near the White House in Washington, D.C., on Monday, striking a bystander before officers returned fire and wounded him. Vice President J.D. Vance's motorcade was leaving the White House and passing through the area as the incident unfolded.

According to a Secret Service affidavit, Marx, of Midland, was walking along the path of Vance's motorcade when officers spotted him carrying a gun near the intersection of 15th Street and Independence Avenue, by the Washington Monument. Federal agents briefly followed him before he tried to run away.

The affidavit states that Marx pulled a firearm from his waistband as he ran and fired at one of the officers, hitting a bystander in the leg. The minor, who was standing behind one of the officers, was not seriously injured.

Officers returned fire, striking Marx in the hand, arm and upper abdomen, according to the affidavit. He collapsed at an intersection and was taken to George Washington University Hospital. Investigators recovered a Sig Sauer P365 handgun from the scene where he fell.

The affidavit says Marx spat at officers as they provided him with aid after the shooting. He made vulgar statements to officers in the ambulance regarding the White House and said, "Kill me, kill me, kill me," according to the affidavit.

A Texas driver's license was found on Marx during a search, and authorities determined he had used the aliases "Patrick Michael" and "Michael Zavici." He does not hold a license to carry a handgun in the District of Columbia. Court records show he had a 2011 drug trafficking conviction in Florida that made it illegal for him to possess a firearm.

Marx was charged in a complaint with assaulting officers with a dangerous weapon, discharging a firearm during a violent crime, and being a felon in possession of a firearm and ammunition. U.S. Attorney Jeanine Pirro vowed to pursue the most serious charges available against Marx or anyone who brings gun violence to the streets of Washington.

"We will prove this defendant carried an illegal firearm into the heart of Washington, D.C., opened fire at Secret Service officers near a crowded intersection, and shot an innocent bystander who was simply crossing the street with his family," Pirro said.
