Donald Trump was evacuated from the White House Correspondents' Association gala after a shooting incident during the dinner, which left attendees in a panic. Trump remarked that the attack would not deter his focus on winning the Iran war, even though he believed it was unrelated to the ongoing conflict.
Around 2,300 guests were dining when the incident unfolded.
Guests were enjoying a spring pea and burrata salad when security rushed in, prompting attendees to get down. The shooter, identified as
Cole Tomas Allen, 31, from Torrance, California, was armed with a shotgun, handgun, and multiple knives. He reportedly opened fire as he rushed toward the ballroom before being subdued by Secret Service agents.
The White House Press Secretary,
Karoline Leavitt, had made a statement earlier indicating there would be "shots fired," raising eyebrows given the timing of the incident. Leavitt described Trump as "ready to rumble" during his speech at the dinner.
Trump characterized the Hilton hotel venue as "not a particularly secure" facility.
He detailed how the shooter aimed at a Secret Service agent, who was saved by his bulletproof vest. The ongoing investigation has been confirmed by the acting US Attorney General, highlighting the gravity of the situation as authorities determine the motive behind the attack.
