On Sunday, President Donald Trump took to Truth Social to address a recent security incident, linking it to the urgent need for the completion of an event hall on White House grounds. He demanded that a lawsuit hindering the project be dismissed immediately.
The security breach occurred on Saturday night at the Washington Hilton during the Annual White House Correspondents' Dinner. Cole Allen, a 31-year-old teacher from Torrance, California, attacked the security checkpoint with a shotgun, pistol, and knives, firing several rounds before being subdued in the lobby by Secret Service agents.
President Trump, First Lady Melania Trump, and Vice President JD Vance were safely evacuated, along with approximately 2,600 attendees. A Secret Service agent was injured, but a bulletproof vest prevented serious harm, and recovery is expected to be complete. Fortunately, no fatalities occurred among the guests.
Trump's Call for Action
In his Sunday post, Trump was unequivocal: "Last night's incident underscores why our military, Secret Service, and law enforcement—and every president for the past 150 years—have demanded a secure and protected event hall on White House grounds."
The president argued that the event wouldn't have happened if it were held in the new, under-construction hall. "This wouldn't have occurred with the top-secret military hall being built at the White House. It can't be finished soon enough!" he stated.
Security Features and Legal Challenges
The planned facility will feature the highest security measures, free from unverified occupants, nestled within the world's most secure perimeter, the White House. Trump criticized the lawsuit filed by the National Trust for Historic Preservation, calling it "ridiculous" and filed by "a dog-walking woman" with no standing. He demanded its immediate dismissal.
The lawsuit cites violations of historical preservation and environmental laws due to partial demolition of the East Wing, built in 1902. A federal judge blocked construction, but an appeals court temporarily allowed it to proceed on April 12.
Project Details and Funding
The new hall will span 90,000 square feet, accommodating 650 to 1,000 people. Trump disclosed in March that the project includes an underground military complex with bulletproof glass and anti-drone ceilings, funded by private donations from companies like Apple, Amazon, Lockheed Martin, and Coinbase, without public funds.
The project's budget has ballooned from an initial $100 to $200 million to $400 million. Construction began on October 20, 2025, with partial East Wing demolition.
Trump concluded his message affirming the project's progress: "Nothing should delay its construction, which is on budget and well ahead of schedule."
Meanwhile, Secret Service Deputy Director Matthew Quinn labeled the attacker a "coward" and noted his swift apprehension. An assistant district attorney announced imminent charges against Cole Allen.
