A man armed with a pistol opened fire on a United States Secret Service checkpoint near the White House on Saturday evening, triggering a sharp exchange of gunfire that left the gunman dead and one bystander critically wounded. The incident unfolded shortly after 6 PM ET near the corner of 17th Street and Pennsylvania Avenue NW, just steps from the White House complex.
The suspect, identified by authorities as Nasire Best, 21, approached the security post, removed a weapon from his bag, and began firing at officers stationed there. Secret Service agents responded immediately, returning fire and striking Best. He was rushed to George Washington University Hospital, where he was later pronounced dead.

A bystander in the vicinity was also struck during the shooting. Law enforcement officials have not confirmed who fired the shot that wounded the bystander; the person is reported to be in critical condition. Yellow crime scene tape cordoned off sections of sidewalk outside the White House complex, with dozens of orange evidence markers placed across the pavement as investigators processed the scene.
Prior history
Court records reviewed by CNN reveal that Best was not unknown to the Secret Service. Officers had previously encountered him multiple times near the White House during the summer of 2025, with documents describing him as someone who would walk around the complex inquiring about entry points. On June 26, 2025, he was involuntarily committed after obstructing vehicle entry to part of the White House grounds. On July 10, 2025, he again entered a restricted area outside the building despite posted warning signs, at which point multiple officers confronted him.
President Donald Trump was inside the White House at the time of the Saturday shooting. A lockdown was placed on the building and the surrounding press area, which confined reporters and correspondents on site. ABC News senior White House correspondent Selina Wang, among others, captured dramatic video of the moment gunfire erupted, describing what she heard as dozens of shots in rapid succession before taking cover.
