The U.S. Secret Service fatally shot a person who opened fire on officers at a security checkpoint on Saturday in an exchange of gunfire that briefly locked down the White House, officials said. The shooting happened shortly after 6 p.m. when a male, later identified as Nesire Best, approached th e Secret Service checkpoint at 17th Street and Pennsylvania Avenue NW, pulled a gun from a bag and opened fire on officers, the Secret Service said in a statement. The officers returned fire and shot the suspect, who was taken to a hospital, where he later died, the Secret Service said. The agency said the shooting remains under investigation. A bystander was also shot, the Secret Service said, but it was unclear who fired the round that injured that person. Their condition was not immediately available. Best had a documented history with local law enforcement and five senior law enforcement officials say he had a history of mental health concerns.  The Secret Service said no agents were injured, and President Donald Trump, who was at the White House at the time, was not injured. The Secret Service briefed Trump about the incident. The suspect is believed to have been known to D.C. police and the Secret Service, three officials said. The person had not been publicly identified Saturday evening. An NBC News team at the White House heard between 20 and 30 gunshots around 6:04 p.m., and Secret Service agents urged reporters who were gathered outside on the North Lawn to run inside the press briefing room. The Secret Service was posted just outside the room with guns drawn as the White House went into lockdown. The lockdown, which included the White House grounds, was lifted at 6:46 p.m. War with Iran 3 hours ago Agreement on Iran war ‘largely negotiated,' Trump says amid fragile ceasefire Vaccines 16 hours ago No child deaths definitively linked to Covid shots, FDA says FBI Director Kash Patel said on X that the FBI is on the scene and supporting the Secret Service.

The shooting occurred on the west end of Pennsylvania Avenue, a pedestrian plaza that runs along the north side of the White House. Days earlier, part of plaza had reopened to the public following a monthslong closure. The U.S. Capitol Police did not immediately respond to a request for information on the situation.
