A 21-year-old man identified as Nasire Best was shot and killed by Secret Service agents Saturday evening after he opened fire near a White House security checkpoint. The incident prompted a massive security response in Washington D.C., as authorities secured the area and began an investigation into the gunman's motives and background. President Donald Trump was inside the White House at the time of the shooting but was confirmed safe, continuing with scheduled national security discussions related to Iran and Middle East tensions.

Law enforcement officials reported that Best, who had a documented history of mental illness, had prior encounters with federal security personnel. According to sources familiar with the investigation, Best had been issued an order in 2025 directing him to stay away from the White House following an earlier security-related incident at one of the checkpoints. Investigators are now reviewing his digital footprint, background, and previous contacts with authorities as they work to determine a clear motive for the attack. A law enforcement source indicated that Best allegedly suffered from severe mental illness and had reportedly referred to himself as Jesus Christ.
The attack unfolded suddenly near a White House security post. Secret Service agents reportedly observed suspicious behavior from Best and identified that he was armed before he discharged multiple rounds. Secret Service personnel quickly returned fire, neutralizing Best. He was transported to a nearby hospital where he was later pronounced dead. No Secret Service agents or other law enforcement personnel were injured during the exchange of gunfire.
One bystander was seriously wounded in the shooting and remains hospitalized. Officials have not yet publicly identified the victim or released updated information regarding their condition. The immediate aftermath of the incident saw journalists and staff scrambling for cover. ABC News correspondent Selina Wang was recording a social media video from the White House North Lawn when the gunfire erupted. Wang later recounted the experience, stating, "I was in the middle of taping on my iPhone for a social video from the White House North Lawn when we heard the shots. It sounded like dozens of gunshots. We were told to sprint to the press briefing room where we are holding now."
Federal authorities currently believe Best acted alone and have not identified any evidence suggesting broader coordination or accomplices. The investigation is also focusing on how Best obtained the firearm used in the shooting and retracing his movements leading up to the incident. Surveillance footage from the area is being reviewed as part of the ongoing inquiry.
The White House confirmed that President Trump remained safe throughout the attack and continued participating in meetings and briefings inside the executive complex. This incident occurs during a period of heightened security concerns in Washington, with the administration actively monitoring geopolitical instability abroad, including tensions involving Iran and various terrorism threats. The investigation into whether Best left behind any writings, manifestos, or online posts that could clarify his intentions before the attack is ongoing, with no public announcements made regarding such findings so far. The swift response by the Secret Service is being highlighted by officials as critical in containing the threat and ensuring the safety of personnel and the President.
