Secret Service Kills Gunman at White House Checkpoint, Bystander Hit

A 21-year-old Maryland man with a documented history of mental illness and prior encounters with White House security opened fire at a checkpoint Saturday evening before Secret Service agents returned fire and killed him. The incident unfolded around 6 p.m. near 17th Street and Pennsylvania Avenue NW, where Nasire Best approached officers, drew a revolver from his bag, and began shooting.

Best, who had been arrested last year attempting unauthorized entry at another White House gate and had violated a court-issued stay-away order, was well known to both the Secret Service and local police. Court records from that earlier episode show he claimed to be Jesus Christ while demanding arrest. Multiple law enforcement sources confirmed he had been flagged as an emotionally disturbed person on prior occasions.

Agents at the checkpoint fired back immediately, striking Best. He was transported to a hospital and pronounced dead. A bystander was also hit during the exchange, though officials have not clarified whether the injury came from Best's shots or those fired by agents. No Secret Service personnel were wounded. President Trump was inside the White House at the time and was not endangered.

Trump later posted on Truth Social that the gunman possessed a violent history and possible obsession with the executive mansion. He praised the agents for their quick response while calling once again for enhanced protection around the complex. The episode marks at least the third reported shooting or security breach near Trump or his events in recent weeks, following gunfire outside the White House Correspondents' Association dinner last month and another incident along Vice President JD Vance's motorcade earlier this month.

The rapid succession of events has renewed questions about how individuals already on security radar continue to reach sensitive perimeters. Best's repeated approaches to White House gates, despite prior arrests and mental health flags, point to gaps in tracking and restricting known threats. Officials have not released a motive, though the pattern suggests failures in follow-through on court orders and prior detentions rather than an isolated lapse.

Roads around the White House remained closed into the night as investigators processed the scene. The Secret Service described the response as standard procedure when an armed individual engages officers at a checkpoint. Bystander accounts captured the sound of sustained gunfire, prompting journalists and staff in the area to seek cover.

This latest breach occurs against a backdrop of heightened alerts around the president. Earlier incidents involved individuals who also appeared to act alone yet still tested perimeter defenses. In Best's case, the fact that he carried a revolver openly enough to be engaged at the gate raises further scrutiny over whether existing protocols sufficiently deter or intercept repeat visitors with documented instability.

Law enforcement sources told outlets that Best had loitered near multiple entry points in the past. His ability to return armed after a prior stay-away order was issued indicates either enforcement shortcomings or inadequate coordination between agencies responsible for monitoring such individuals. The wounded bystander adds another layer of public risk from these encounters.

Trump has emphasized the need for stronger physical security measures around the White House. Saturday's shooting provides fresh evidence that current arrangements leave room for determined actors to reach firing range. As details continue to emerge, the focus remains on why a person with Best's record was not more effectively contained before the confrontation escalated.
