A Secret Service shootout with an armed man near the Washington Monument on Monday afternoon sent journalists scrambling into the White House briefing room and shut down streets across the heart of the nation's capital, the second serious security incident in the area in barely a week.
The confrontation began at approximately 3:30 p.m. EDT when plainclothes Secret Service officers patrolling the outer perimeter of the White House complex spotted a man who appeared to be carrying a firearm near 15th Street and Independence Avenue, just a few blocks south of the Washington Monument. Secret Service Deputy Director Matthew Quinn told reporters that agents called for backup from uniformed Secret Service police to make contact with the individual.
What followed was a brief foot chase and a gunfight on one of the most heavily visited stretches of federal land in the country. The man fled, drew his weapon, and opened fire on the agents and officers pursuing him. They returned fire and struck him. A juvenile bystander was also hit. Both were transported to a hospital, and Quinn said the bystander's injuries were not life-threatening.
Just The News reported that the suspect was identified as Michael Marx, 45, who was reportedly carrying a Texas driver's license. No motive has been established. Quinn said the agency had not yet determined why Marx was armed near the White House perimeter.
A weapon was recovered from the scene. The Secret Service has not publicly described the type of firearm.
D.C.'s Metropolitan Police Department confirmed it was on scene and declared the area secure in a post on X:
"MPD is on scene of this investigation at 15th Street and Independence Ave, SW. The scene is secure. Avoid the area as roads will be closed for several hours. Additional updates to come as information is confirmed."
The intersection sits just south of the Washington Monument, roughly a mile from the White House itself. That distance matters, the shooting did not occur on the White House grounds, but the proximity to the executive mansion was close enough to trigger an immediate security response that reached the North Lawn.
Reporters stationed on the North Lawn were escorted off immediately after the gunfire and sheltered inside the briefing room until they received an all clear, The Hill reported. President Trump was inside the White House at the time, delivering remarks at a Small Business Summit. The White House referred questions to the Secret Service.
Vice President Vance's motorcade had transited through the area before the shooting took place, the Secret Service said. There was no indication either the president or vice president was in danger, but the rapid lockdown underscored how seriously the agency treated the threat.
The New York Post reported that the media evacuation was triggered directly by the shootout, with law enforcement moving journalists inside as part of a broader safety lockdown while the response unfolded south of the White House complex.
Monday's incident came a little more than a week after a man armed with a handgun, a shotgun, and several knives ran past security during the White House Correspondents' Association annual dinner. That earlier breach exposed glaring gaps in event security and raised immediate questions about how an armed individual could get so close to a gathering packed with senior government officials and members of the press.
Quinn described the plainclothes patrol that spotted Marx as a routine element of the Secret Service's outer-perimeter operations. His account of the sequence was methodical:
"This afternoon our plain clothes officers and agents that consistently patrol the outer perimeter of the White House complex identified a suspicious individual that appeared to have a firearm. They called in support from our marked uniform Secret Service police to make contact with that individual."
The system, in other words, worked as designed on Monday. Agents identified a threat, called for uniformed backup, and engaged the suspect after he fired first. But the fact that a gunman was able to open fire within a mile of the White House, and wound a child in the process, is not a reassuring data point when it follows so closely on the heels of the Correspondents' Dinner breach.
That earlier incident prompted Vice President Vance himself to describe the chaotic evacuation from the dinner, and it drew sharp criticism from security professionals who warned that the vulnerability could be exploited by far more dangerous actors.
Quinn confirmed the bystander struck by the suspect's gunfire was a juvenile. He framed the injury carefully:
"I can tell you that at least one, we believe only one bystander was hit by the suspect. That individual, it's a juvenile, did not sustain any life-threatening injuries, but he's also receiving treatment at the hospital."
A child caught in a crossfire near the Washington Monument on a Monday afternoon. That fact alone should concentrate minds in Washington about what the security perimeter around the executive mansion actually looks like in practice.
Much remains unknown. The Secret Service has not disclosed what type of weapon Marx carried or whether he has been formally arrested and charged. His condition at the hospital has not been publicly updated. Whether he had any connection to the White House, any political motivation, or any prior criminal history, none of that has been established.
Former intelligence professionals have already warned that the security gaps revealed by the Correspondents' Dinner attack could be exploited by hostile foreign actors. Monday's shooting, while apparently a different kind of incident, will only sharpen those concerns. Two armed confrontations within roughly ten days, both within the broader security zone surrounding the White House, form a pattern that federal law enforcement cannot afford to treat as coincidence until they have ruled it out.
Roads around the scene remained closed for several hours Monday evening as investigators processed the area. The Metropolitan Police Department said additional updates would come as information was confirmed.
The recent string of security incidents near the White House has tested the agencies responsible for protecting the president, the vice president, and the thousands of tourists and workers who pass through the National Mall every day. Monday's outcome, agents spotted the threat, engaged it, and contained it, was far better than the alternative. But a juvenile is in the hospital, a gunman got close enough to fire on federal officers in broad daylight, and the motive remains unknown.
When the perimeter holds only after shots are fired, the perimeter isn't holding. It's reacting.
