WASHINGTON, D.C. — A night meant for camaraderie and light-hearted exchanges veered into chaos on Saturday when gunshots erupted at the Washington Hilton during the White House Correspondents’ Dinner, an event attended by President Donald Trump.

The suspect, identified by authorities as 31-year-old Cole Allen from Torrance, California, had allegedly crafted a manifesto and shared alarming social media posts, revealing his intentions to target President Trump and other members of the administration.

According to law enforcement, Allen’s sister, Avriana Allen, informed the Secret Service and Montgomery County Police about her brother’s history of making extreme statements. She indicated that he had previously spoken about plans to “do something” to address what he perceived as societal issues.

In a sudden turn of events, Allen reportedly burst into the lobby of the Washington Hilton, armed and ready, shortly after the dinner commenced. However, the swift response by Secret Service agents led to his immediate apprehension.

Currently in custody, Allen faces the prospect of federal charges, which are anticipated to be filed by authorities on Monday.

Blanche added that it appears Allen bought the guns in “the past couple of years.”

“That could be another reason why he traveled by train because he had the firearms with him, but I’m speculating there,” he said.
