Suspect Dead After Opening Fire at White House Security Checkpoint
A 21-year-old man from Maryland opened fire near a White House security checkpoint on Saturday evening and was fatally shot by Secret Service officers who returned fire, according to the U.S. Secret Service. A civilian bystander was also wounded during the exchange. President Donald Trump was inside the White House at the time and was not harmed.
The Incident
The shooting occurred shortly after 6:00 p.m. EDT at the intersection of 17th Street and Pennsylvania Avenue NW, a heavily secured checkpoint on the northwest edge of the White House complex. The suspect, identified by law enforcement officials as Nasire Best, approached the checkpoint, pulled a handgun from his bag, and began firing toward the White House, according to the Secret Service.
Officers stationed at the checkpoint returned fire, striking Best. He was transported to a local hospital, where he was pronounced dead. The Secret Service confirmed that none of its officers were injured. The White House was placed under lockdown for approximately 40 minutes before the all-clear was given.
A civilian bystander was also struck by gunfire during the exchange, though authorities said it remains unclear whether the bystander was hit by the suspect’s initial shots or by officers’ return fire. The condition of the wounded bystander has not been publicly disclosed.
Suspect’s Background
Nasire Best had a documented history of encounters with the Secret Service. According to District of Columbia court records, Best was arrested in July 2025 after attempting to enter a different White House checkpoint without authorization. During that incident, he did not heed officers’ commands to stop, claimed he was Jesus Christ, and said he wanted to be arrested.
A “Pretrial Stay Away Order” was issued by D.C. courts, a measure typically ordering a defendant to stay away from a person or area before trial. A bench warrant was issued in August 2025 after Best failed to comply with the order, though he did appear for a subsequent hearing. Best had also been detained by the Secret Service in June 2025 for flagging down agents and making threats.
Third Security Incident in a Month
Saturday’s shooting marks the third instance of gunfire near President Trump in the past month. On April 25, an attempted assassination occurred at the White House Correspondents’ Association Dinner at the Washington Hilton, where suspect Cole Tomas Allen allegedly ran through a security checkpoint and fired a shotgun at a Secret Service officer. Allen has pleaded not guilty to charges of attempting to kill the president.
On May 4, Secret Service officers shot a suspect near the Washington Monument, several blocks from the White House. Michael Marx, 45, of Midland, Texas, was charged with assaulting officers with a dangerous weapon after allegedly firing at law enforcement. A teenage bystander was wounded in that incident.
The shooting scene is also within walking distance of where a gunman ambushed two members of the West Virginia National Guard in November 2025, killing U.S. Army Specialist Sarah Beckstrom, 20, and critically wounding Staff Sgt. Andrew Wolfe.
Official Reactions
President Trump praised law enforcement’s response in a social media post, thanking the “great Secret Service and Law Enforcement for the swift and professional action taken this evening against a gunman near the White House.” He noted the incident “goes to show how important it is, for all future presidents, to get, what will be, the most safe and secure space of its kind ever built in Washington, D.C.”
FBI Director Kash Patel confirmed that FBI personnel were on the scene supporting the Secret Service investigation. Secretary of Homeland Security Markwayne Mullin said he was “closely monitoring the shooting incident” and called it “a reminder of the dangers our law enforcement officers face every day.”
House Speaker Mike Johnson expressed gratitude for the “brave Secret Service agents who took quick, decisive action to protect President Trump,” while New York Governor Kathy Hochul condemned political violence, stating that “the quick actions of the Secret Service tonight prevented an already dangerous situation near the White House from becoming even worse.”
Analysis and Implications
The frequency of security incidents — three involving gunfire near the president in just one month — has raised serious questions about the adequacy of security perimeters around the White House. Best’s prior encounters with the Secret Service and documented history of mental health issues highlight ongoing challenges in threat assessment and intervention.
As Al Jazeera correspondent Kimberly Halkett noted, “These incidents are happening with increasing frequency.” The shooting also occurred amid heightened security concerns and ongoing sensitive negotiations between the Trump administration and Iran, adding further complexity to the security environment.
What’s Next
The FBI and Secret Service continue to investigate the incident, including the suspect’s motive and how he obtained the firearm. Questions remain about the condition of the wounded civilian bystander and whether the recent spate of security incidents will prompt changes to White House security protocols. The case also raises broader questions about the enforcement of stay-away orders and the effectiveness of existing threat assessment mechanisms for individuals with documented mental health concerns and prior security encounters.
