May 24 (UPI) — The gunman who opened fire at the White House this weekend before being fatally shot by Secret Service officers has been identified as Nasire Best, unnamed sources confirmed to multiple media outlets.

The 21-year-old had previous encounters with the Secret Service and had previously posted threatening statements online, the sources told CBS News, NBC News and CNN. The sources said Best had never acted violently or brandished a weapon prior to Saturday evening, when police said he approached a checkpoint at the White House, pulled a firearm from his bag and opened fire.

Officers returned fire, striking Best, who was transported to a hospital where he was declared dead, Anthony Guglielmi, chief of communications for the Secret Service, said in the statement.

A bystander was also injured in the shooting and was in critical condition.

“It remains unclear whether the bystander was struck by the suspect’s initial gunfire or during the subsequent exchange of gunfire,” a Secret Service representative told CNN.

President Donald Trump, who was inside the residence at at the White House at the time of the shooting, was unharmed. In a post on Truth Social just after midnight Sunday, Trump thanked the Secret Service for their actions during the shooting.

“Thank you to our great Secret Service and Law Enforcement for the swift and professional action taken this evening against a gunman near the White House, who had a violent history and possible obsession with our Country’s most cherished structure,” Trump wrote.

Sources told CNN that Best had been detained in June 2025 and committed to the Psychiatric Institute of Washington for evaluation after he blocked an entry lane at the White House and proclaimed he was God. A month later, the Secret Service arrested him after he allegedly tried to enter a White House driveway. A judge told him to keep away from the White House.

Investigators at the time said they found that he had made statements online saying he wanted to hurt Trump and that he was the real Osama bin Laden, the mastermind behind the Sept. 1, 2001, terror attacks.

Trump also took the opportunity in his Truth Social post to renew his stance that the new ballroom he’s constructing would serve as added security at the White House.

“This event is one month removed from the White House Correspondent’Dinner shooting, and 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. The National Security of our Country demands it!”

May 23 (UPI) — The White House was locked down on Saturday evening after a man approached one of its checkpoints and opened fire at the executive mansion before being shot by the Secret Service.

Around 6 p.m. a man near 17th Street and Pennsylvania Avenue approached a White House entrance, pulled a firearm from his bag and started firing at the entrance, the Secret Service said in a statement.

Members of several media organizations, some who were reporting live, reported hearing what they thought were gunshots before the Secret Service told them to seek shelter inside the James S. Brady Press Briefing Room.

“Secret Service Police returned fire, striking the suspect, who was transported to an area hospital where he was pronounced deceased,” Anthony Guglielmi, chief of communications for the Secret Service, said in the statement.

“During the shooting, one bystander was also struck by gunfire,” Guglielmi said. “No injuries were sustained by officers.”

The bystander is in serious condition, CBS News reported.

The Secret Service said that President Donald Trump, who has been working at the White House all day amid negotiations to end the Iran war, was in the White House during the shooting, “however no protectees or operations were impacted.”

Reporters on the North Lawn reported that they heard what they thought was gunfire and ducked before Secret Service agents told them to “sprint to the press briefing room” to take cover.

Both the Secret Service and FBI quickly confirmed that both agencies were investigating reports of gunfire near the White House.

The White House was briefly locked down, and The Washington Post reported that its security gates remained locked hours after the incident.

The White House checkpoint the man fired at is located at 17th Street and Pennsylvania Avenue, which is near the Eisenhower Executive Office Building.

Although the suspect approached the White House, Fox News reported that he never actually got inside the general perimeter of the executive mansion.

April 25 (UPI) — President Donald Trump said Sunday a suspect arrested in connection with a shooting at the White House Correspondents’ Association Dinner in Washington, D.C., had written an anti-administration “manifesto.”

Other reports indicated the suspect, identified as Cole Thomas Allen, 31, of Torrence, Calif., had sent a communication to family members minutes before the late Saturday incident at the Washington Hilton Hotel

In the note, he reportedly said he was targeting members of the Trump administration in his attack.

Trump told Fox News Allen’s “manifesto” indicated he “is a sick guy.

“When you read his manifesto, he hates Christians. That’s one thing for sure. He hates Christians, a hatred. And I think his sister or his brother actually was complaining about it. You know, they were even complaining to law enforcement. So he was, he was a very troubled guy.”

Security camera footage supplied by the White House showed a man charging through a security checkpoint outside the hotel ballroom where the correspondents’ dinner was being held.

The Washington Metropolitan Police Department said one person was in custody in connection with the incident and it is believed he acted alone. Two firearms and multiple knives were recovered at the scene and a Secret Service Uniformed Division officer was injured and hospitalized with “non-life threatening injuries,” they added.

The White House told Fox Sunday Allen’s family members had notified the New London, Conn., police department on Saturday when they received the communication. Administration officials also claimed Cole Allen’s sister, Avriana Allen, told the Secret Service her brother had been making “radical” statements and was in possession of weapons.

Meanwhile, NBC News reported the communication shows Allen apologized to his parents, colleagues, students, bystanders and others for what he was about to do.

“I don’t expect forgiveness,” Allen reportedly wrote. “Again, my sincere apologies.”

He also reportedly criticized the president without specifically mentioning him and noted that security precautions at the hotel were not as stringent as he had expected them to be.

Administration officials “are targets, prioritized from highest-ranking to lowest,” he wrote, according to NBC News, adding, “I experience rage thinking about everything this administration has done.”

The New York Times reported federal authorities in Los Angeles served a search warrant on Allen’s house in Torrance but refused to comment on Trump’s assertion that Allen had penned a “manifesto” before correspondents’ dinner attack.

Acting U.S. Attorney General Todd Blanche said a preliminary investigation had determined the suspect “traveled by train from Los Angeles to Chicago, and then Chicago to Washington, D.C., where he checked into the hotel where the correspondent’s dinner was at in the last day or two.”

On NBC’s Meet the Press, Blanche said authorities believe that the two firearms the suspect carried during the attack had been purchased “within the past couple of years,” adding, “We believe that he was targeting administration officials in this attack, attempted attack. But that’s, again, quite preliminary as law enforcement continues to go through all the evidence.”

U.S. Attorney for the District of Columbia Jeanine Pirro told reporters Allen is expected to be arraigned Monday. He is facing two preliminary charges including using a firearm during a crime of violence and assault on a federal officer using a dangerous weapon.

Media analyses of Allen’s social media accounts portray him as self-described independent computer game developer, including a game called “Bohrdom” that was released in 2018. He reportedly earned an undergraduate degree in mechanical engineering at the California Institute of Technology.

At a press briefing after returning to the White House following the incident, Trump said he believed that this was a “lone wolf” attack as he praised the response of Secret Service and law enforcement after recognizing the threat.

Trump said there was no indication of a motive, political or otherwise, but that “we’ll find out very quickly” about this “very sick person.”

Allen has been taken to the hospital, as has the Secret Service agent who was injured, The Washington Post reported.

Dinner was being served at the annual gathering of the Washington press organization when shots could be heard from the ballroom, causing many in the room to freeze.

President Trump, Melania Trump and other members of the administration on the dais and in the ballroom were evacuated within minutes of shots being heard over C-SPAN and other networks broadcasts.

As the officials were cleared from the room, Secret Service agents swarmed it and ordered other guests to stay in their seats.

Trump said in a post on Truth Social that he wanted to return to the dinner and for the “SHOW TO GO ON,” but security insisted that they leave the hotel and return to the White House.

Most of the other guests remained in the ballroom after organizers made an announcement that the show would continue shortly.

There was also speculation whether Trump would return to the dinner after the announcement the show would continue and the Presidential Seal was not immediately removed from the podium on the dais.

“Law Enforcement has requested that we leave the premises, consistent with protocol, which we will do immediately,” Trump posted about an hour after the incident.

“The First Lady, plus the Vice President, and all Cabinet members, are in perfect condition,” Trump posted. “I have spoken with all the representatives in charge of the event, and we will be rescheduling within 30 days.”

An announcement in the ballroom mirrored Trump’s announcement about rescheduling the dinner for next month.

C-SPAN reported that waiters started to clear the salad portion of dinner as guests started to open wine while waiting for more information about the situation before the announcement that the dinner is going to be rescheduled.

April 25 (UPI) — President Donald Trump returned to the White House after a shooting incident at the White House Correspondents’ Association Dinner in Washington, D.C.
