The gunman who opened fire at a White House security checkpoint on Saturday evening has been identified as Nasire Best, 21, who had a history of mental illness and prior encounters with Secret Service and local law enforcement.

Best, who had been issued a stay-away order from the White House in 2025, fired multiple shots before being fatally shot by return fire.

One bystander was seriously wounded.

President Trump and White House staff were unharmed and continued working inside.

The FBI and Secret Service are investigating the motive.
