A pellet from the shotgun fired by the man charged with trying to assassinate President Donald Trump at the White House Correspondents' Association dinner struck a Secret Service agent and lodged in the officer's bullet-resistant vest, U.S. Attorney for the District of Columbia Jeanine Pirro said Sunday.

Pirro told CNN's "State of the Union" that forensic analysis had linked the buckshot directly to the Mossberg pump-action shotgun carried by 31-year-old Cole Tomas Allen of Torrance, California, who faces charges including attempted assassination of the president.

The finding matters because it eliminates any remaining question about whether the agent was hit by friendly fire during the chaotic exchange of gunfire on April 25. Pirro had said last week that there was no evidence of friendly fire. Now, she said, the physical proof is conclusive.

Pirro: 'It is definitively his bullet'

Appearing on the Sunday broadcast, Pirro described the forensic link in precise terms:

"We now can establish that a pellet that came from the buckshot from the defendant's Mossberg pump-action shotgun was intertwined with the fiber of the vest of the Secret Service officer."

She added flatly: "It is definitively his bullet."

The Secret Service agent survived the attack. Allen was also injured during the incident but was not shot, Pirro said. He remains behind bars pending trial.

If convicted on the attempted assassination count alone, Allen faces up to life in prison. He also faces two additional firearms charges, including discharging a weapon during a crime of violence.

A calculated cross-country trip

The attack on April 25 unfolded at a Washington hotel where the annual White House Correspondents' Association dinner was underway. Authorities say Allen ran through a security checkpoint toward the ballroom packed with journalists, administration officials, and others, armed and ready to kill.

Police said Allen carried a shotgun, a handgun, and multiple knives when he charged the checkpoint, the Washington Free Beacon reported. Law enforcement exchanged gunfire with Allen before apprehending him.

The Justice Department has argued in court filings that Allen traveled across the country with the explicit aim of killing the president. A DOJ filing seeking to keep Allen detained stated the case bluntly.

Fox News reported that the filing included a photo showing Allen armed inside his hotel room before the attack and laid out the government's argument for pretrial detention:

"Detention is warranted based on the gravely serious and highly calculated nature of the defendant's crimes, the overwhelming evidence of his guilt, and the intolerable risk that he will again resort to extreme violence to register political disagreement."

Pirro has handled several high-profile federal matters since taking over as the top federal prosecutor in Washington. In this case, she has signaled that additional charges against Allen may follow as the investigation continues.

Selfies, a manifesto, and anti-Trump posts

Court documents filed by prosecutors paint a picture of a man who prepared methodically. Just The News reported that the government submitted selfies allegedly taken by Allen shortly before the attack. Prosecutors said the photos show him carrying a small leather bag "consistent in appearance with the ammunition-filled bag later recovered on his person," along with a shoulder holster, a knife, pliers, and wire cutters.

The evidence suggests Allen did not stumble into this moment. He equipped himself, documented himself, and moved toward the ballroom.

His alleged motive appears rooted in intense political hostility toward the president and his administration. The Washington Free Beacon reported that Allen had amplified posts on the social media platform Bluesky calling for Trump to be "immediately removed from office and tried for high crimes." He reportedly contributed $25 to Kamala Harris's presidential campaign and reposted other strongly anti-Trump messages before the event.

Prosecutors also cited a manifesto in which Allen allegedly wrote about targeting administration officials, listing them "from highest-ranking to lowest," National Review reported. The document referred to officials other than CIA Director Kash Patel as "targets."

That level of premeditation, a cross-country trip, a written target list, weapons, ammunition, and selfies taken in tactical gear, goes well beyond a spontaneous act. It describes a planned assassination attempt.

The scene and its aftermath

On Thursday, days before her Sunday television appearance, Pirro posted a video on social media showing the moment authorities say Allen attempted to storm the media gala. The footage gave the public its most direct look at the chaos that unfolded outside the ballroom.

President Trump himself described the moments during the shooting, saying he slowed his own Secret Service evacuation during the incident, a detail that underscored just how close the danger reached.

Allen's defense attorneys filed a document with the court on Sunday as well, though its substance was procedural. The filing stated that Allen was no longer on suicide watch and sought to withdraw a prior motion that had formally requested his removal from that supervision.

The defendant remains in custody. No trial date has been publicly set.

A pattern of escalation the country cannot ignore

This is the latest in a series of security threats directed at President Trump and those around him. The forensic confirmation that Allen's buckshot struck a Secret Service agent's vest is not a minor detail. It establishes, in physical terms, that a man motivated by political rage fired a weapon at a federal officer protecting the president, and that the round made contact.

Pirro, who has not shied away from aggressive action in her role as U.S. attorney, appears to be building a methodical case. She has publicly laid out the forensic findings, released video of the attack, and signaled that more charges could come.

The question now is whether the broader political and media culture that fuels the kind of rhetoric Allen consumed and amplified will face any serious reckoning. A man read posts calling for a president to be "tried for high crimes," wrote a manifesto ranking administration officials as targets, armed himself, drove across the country, and opened fire at a gala dinner. The chain from rhetoric to action is not abstract here. It is documented in court filings.

Open questions remain. What was the full content of Allen's manifesto? Will additional charges reflect the scope of his alleged planning? And will the institutions that host and amplify the most reckless political rhetoric acknowledge any connection to the violence it can produce?

When a pellet from a shotgun ends up woven into the fibers of a Secret Service agent's vest, the country is not dealing with overheated speech. It is dealing with consequences.
