US Attorney Jeanine Pirro confirmed the bullet that struck a Secret Service agent during the White House Correspondents’ Dinner shooting “definitively” came from the weapon used by Cole Allen, the man accused of attempting to assassinate President Donald Trump.

“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,” Pirro told Jake Tapper on CNN’s State of the Union.

“It is definitively his bullet he hit at that Secret Service agent. He had every intention to kill him, and anyone who got in his way, on his way to killing the President of the United States,” Pirro continued. “This was a premeditated, violent act, calculated to take down the president, and anyone who was in the line of fire.”

The suspect, 31-year-old Cole Allen, ran past a security checkpoint at the Washington Hilton hotel, where the dinner was being held. He was able to breach the security perimeter before firing a shotgun and was later apprehended by Secret Service agents. Allen has since been charged with three federal crimes, including attempting to assassinate the president.

According to reports, Allen travelled from California to Washington by train with a shotgun, a .38 caliber pistol, and multiple knives and daggers. Legal filings submitted last week stated that Allen was “willing to commit a mass shooting inside a room full of the highest-ranking officials in the US government.”

Social media posts linked to the suspect that surfaced after the incident reportedly showed him comparing Trump to Adolf Hitler. He also had encouraged critics of the Trump administration to purchase firearms.
