A shooting incident occurred at a White House security checkpoint on Saturday, resulting in the death of the shooter, identified as 21-year-old Nasire Best from Maryland. Authorities reported that Best had a documented history of encounters with law enforcement and mental health issues. President Donald Trump acknowledged the swift response of the Secret Service and law enforcement in a post on Truth Social.
Best had previously been known to the Secret Service and had been arrested for unlawful entry into a restricted area of the White House complex in July 2025. He had also been involuntarily committed in June 2025 after obstructing vehicle entry to the White House. Following his July arrest, a stay-away order was requested to prevent him from entering the White House area.
On Saturday evening, Best approached a checkpoint near 17th Street and Pennsylvania Avenue NW, pulled a firearm from a bag, and opened fire on Secret Service officers. Officers returned fire, striking Best, who was later pronounced dead at a hospital. A bystander was also injured, but details regarding their condition or the circumstances of their injury have not been disclosed. No Secret Service agents were harmed during the incident.
The White House was placed on lockdown during the event, which was lifted at 6:46 p.m. ET. The FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives are assisting in the ongoing investigation, and as of early Sunday, no motive for the shooting has been announced.
