White House Gunman Had Multiple Prior Run-Ins With Secret Service

When 21-year-old Nasire Best opened fire outside the White House on Saturday, it wasn’t his first brush with the agency that protects the president. Court records and law enforcement accounts paint a troubling pattern stretching back to 2025—a series of escalating encounters that culminated in the deadly shootout that left Best dead and another person injured.

The trajectory is hard to ignore. Best had been stopped by the Secret Service at least twice before Saturday’s confrontation. In one incident last year, he allegedly blocked vehicle access to part of the White House grounds and was involuntarily committed to a psychiatric hospital as a result. Weeks later, he was apprehended again after walking into a restricted area near the complex, where he reportedly told officers he was Jesus Christ and wanted to be arrested. These weren’t random trespassing incidents—they were deliberate attempts to breach security at one of the nation’s most protected locations.

But the encounters with law enforcement tell only part of the story. In the weeks leading up to Saturday, Best posted disturbing messages online that signaled serious psychological distress. He claimed to be the son of God and posted content that appeared to threaten Donald Trump. The digital breadcrumbs were there, visible to anyone scrolling through his accounts, yet they apparently didn’t trigger the kind of intervention that might have prevented what came next.

When Best approached a security checkpoint on Saturday and allegedly opened fire, Secret Service agents returned fire, killing him. Another person nearby was struck in the exchange. President Trump, who was inside the White House at the time, later praised the agents’response on Truth Social, calling it“swift and professional action”and describing Best as a man with a“violent history and possible obsession”with the White House.

What emerges from the details is a man in crisis, cycling through the system without finding the help he needed. The psychiatric commitment, the repeated trespassing attempts, the online threats—these were warning signs that didn’t prevent tragedy. It raises uncomfortable questions about how law enforcement and mental health systems identify and assist people in severe distress before they reach a breaking point, and whether previous encounters should have triggered a different kind of response. The swift professional action on Saturday neutralized an immediate threat, but the larger question lingers: what happens before the shooting starts?
