Secret Service agents shot and killed 21-year-old Nasire Best on Saturday, May 23, 2026, after he opened fire near a White House security checkpoint at 17th Street and Pennsylvania Avenue NW. One bystander was wounded in the exchange, though President Donald Trump, who was inside the building, remained unharmed.
The 17th Street Security Breach
The violence erupted shortly before 6:00 p.m. ET on Saturday near the Eisenhower Executive Office Building. According to officials, the suspect approached a security checkpoint, pulled a firearm from a bag, and began firing. The response from the Secret Service was immediate and lethal.

The scale of the engagement was significant for a metropolitan security zone. The BBC reported that between 10 and 20 shots were fired during the encounter. While no federal agents were injured, the gunfire caught a passerby in the crossfire. The identity and condition of that bystander remain unconfirmed, as does the origin of the bullet that struck them.

At the time of the shooting, President Trump was in the Oval Office working with a circle of advisors, including Steven Cheung, Natalie Harp, and Margo Martin. The White House was cordoned off for roughly an hour, but the agency maintained that “none of the protected persons or any operations were affected.”
Nasire Best and the July 2025 Warning
The identity of the shooter, Nasire Best, reveals a critical gap in the security perimeter’s long-term memory. This was not a random encounter with a stranger; Best had already been on the Secret Service’s radar.
In July 2025, Best was detained by the Secret Service after attempting to enter the White House. Following that incident, he was placed in a psychiatric center to address mental health struggles. The fact that a previously detained individual with a history of attempting to breach the grounds was able to return and open fire at a checkpoint raises inevitable questions about the efficacy of post-detention monitoring and the coordination between mental health facilities and federal security.
Chaos in the North Garden

For the journalists stationed at the White House, the event was a sudden transition from routine reporting to a survival scenario. Several reporters were recording segments when the detonations began, forcing an immediate evacuation to the press room.
Selina Wang, a correspondent for ABC News, captured the moment on video, filming herself diving for cover in the North Garden. She described the auditory experience as sounding like “dozens of shots.”

The physical aftermath left a stark visual record on the sidewalk outside the complex. Investigators deployed dozens of orange evidence markers across the pavement, surrounded by yellow crime scene tape and discarded medical supplies, including purple surgical gloves and emergency kits.
Three Attacks in Thirty Days
This incident is not an isolated anomaly but the peak of a volatile month. As the San Antonio Express-News noted, this marks the third time in the last 30 days that gunfire has occurred in the immediate vicinity of the president.
April 2026: An armed individual opened fire during the White House Correspondents’ Dinner.
Early May 2026: A shooting incident occurred near the Washington Monument.
May 23, 2026: The lethal exchange at the 17th Street and Pennsylvania Avenue checkpoint.
While the president was never in direct peril during the April incident, the frequency of these events suggests a deteriorating security environment or a concerted spike in targeted aggression. The transition from the outskirts (Washington Monument) to the very gates of the executive residence indicates an escalation in proximity and boldness.
The Forensic Trail and FBI Response
The federal response has been swift, with the FBI moving in to support the Secret Service’s primary investigation. FBI Director Kash Patel confirmed the agency’s presence on-site, signaling that the investigation will likely look beyond the immediate act of violence to determine if there were broader conspiracies or failures in intelligence.

The immediate focus for investigators will be the contents of the bag Best used to conceal his weapon and any electronic devices he carried. With the suspect dead, the narrative of the attack now rests entirely on forensic evidence and the timeline of Best’s movements since his 2025 psychiatric commitment.
The primary uncertainty remaining is the status of the wounded bystander. In a high-stakes environment where 10 to 20 rounds are exchanged in a public space, the liability and the tragedy of collateral damage often overshadow the tactical success of neutralizing a threat. For now, the city’s most secure perimeter remains on high alert.
