A man fatally shot by Secret Service agents outside the White House this morning had a history of attempting to breach the presidential premises, having made two prior attempts last year.
Identified by three sources, the shooter was 21-year-old Nasire Best, who approached a security checkpoint and began firing at agents earlier today, Australian time.
According to preliminary findings, the incident occurred shortly before 6 p.m. Saturday ET (8 a.m. Sunday AEST) when Best approached a checkpoint near the White House complex and opened fire on officers, as reported by a Secret Service representative.
In response, the Secret Service officers returned fire, critically wounding Best, who was later pronounced dead at a nearby hospital, the spokesperson confirmed.
During the exchange, a bystander was also hit by gunfire. The spokesperson noted it is still uncertain whether the bystander was struck by Best’s initial shots or during the officers’ return fire.
Investigators recovered a pistol they believe belongs to the suspect, an anonymous official previously said.
Best had previous encounters with the Secret Service, one law enforcement source said, including an incident in June 2025 in which he blocked an entry lane at the White House.
After claiming he was “God,” he was detained by the Secret Service and committed to the Psychiatric Institute of Washington for mental evaluation, the source said.
The following month, in July 2025, the Secret Service arrested Best again after he attempted to enter a White House complex driveway, the source said. A judge issued an order demanding he stay away from the White House grounds.
While investigating the encounters last year, investigators discovered Best had made various statements on social media, including claiming he was “the real” Osama bin Laden, and at least one post indicating his desire to harm Trump, the source said.
But police had never encountered the suspect behaving violently or wielding a weapon before, according to a law enforcement source.
Trump was at the White House during the shooting but was unaffected, and has been briefed on the incident, according to a spokesperson.
The building was locked down for about 40 minutes but has since returned to normal.
“It sounded like dozens of gunshots. We were told to sprint to the press briefing room where we are holding now.”
A Secret Service official told CNN that the agency was investigating reports of shots fired at the corner of 17th Street and Pennsylvania Avenue Northwest, which is just outside the White House complex.
Secret Service agents carrying rifles could be seen moving through the North Lawn area following the incident and blocking the White House press briefing room.
The Secret Service said it was “aware of reports of shots fired near 17th Street and Pennsylvania Avenue NW” — one block from the White House — and was “working to corroborate the information with personnel on the ground”.
In a social media post, FBI Director Kash Patel said officers were responding to shots fired and said he would “update the public as we’re able.”
The lockdown comes a month after the White House Correspondents’ Dinner, where reporters and Trump administration officials ducked for cover as shots rang out.
The suspect in that shooting, Cole Tomas Allen, sprinted through a security checkpoint with a shotgun in hand, exchanging fire with Secret Service agents who chased behind him, according to security footage.
He has pleaded not guilty to attempting to assassinate Trump and to other charges.
