The Trump Justice Department moved swiftly Sunday to pressure the National Trust for Historic Preservation into dropping its lawsuit against the president's planned White House ballroom, citing the armed attack at the Washington Hilton during Saturday night's White House Correspondents' Association dinner as proof the project is a security necessity.
Acting Attorney General Todd Blanche posted a letter to social media giving the preservation group until 9:00 a.m. Monday to voluntarily dismiss its case. If it refused, Blanche warned, the government would move to dissolve the existing injunction and seek dismissal on its own.
The group refused. Its lawyer responded that the lawsuit would continue, setting up a direct collision between the administration's security argument and a legal challenge that has already bounced between a district court and a federal appeals panel since December. The Hill first reported the DOJ's demand and the preservation group's refusal on Sunday.
Blanche's letter framed the Saturday night shooting as a turning point in the legal fight. A gunman exchanged fire with law enforcement at the Washington Hilton, where the WHCA hosted its annual dinner, prompting the evacuation of President Trump and high-profile administration officials from the gala.
In the letter, Blanche wrote:
"If your client does not dismiss the lawsuit by 9:00 AM on Monday, the government will move to dissolve the injunction and dismiss the case in light of last night's extraordinary events."
A separate DOJ letter, sent by Assistant Attorney General Brett Shumate, was even more pointed. Fox News reported that Shumate wrote directly to the preservation group's attorney, Gregory Craig, telling him the lawsuit "puts the lives of the President, his family, and his staff at grave risk."
The DOJ described the proposed ballroom as a hardened facility, 90,000 square feet, with reinforced concrete and steel, bulletproof glass, drone-resistant roofing, and integrated security systems, Newsmax reported. The estimated cost: $400 million, privately funded.
The National Trust for Historic Preservation filed its lawsuit in December, requesting an injunction to halt the ballroom project and ensure the public had a chance to weigh in on changes to the White House grounds. The case landed before U.S. District Judge Richard Leon, who in late March paused construction entirely.
Leon said no statute "comes close" to giving the president the authority he claimed to proceed with the project, and he stopped construction until Congress authorized its finalization. A few days later, Leon narrowed his order, restricting the project to below-ground construction only.
But the administration didn't wait long. A three-judge federal appeals panel allowed construction on the ballroom to go forward into June, and the case remains active. That appeals panel has scheduled a June 5 hearing to review the dispute, the Washington Times reported.
The recent leadership changes at the Justice Department have not slowed its willingness to intervene aggressively in politically charged legal disputes. Under Blanche's acting leadership, the DOJ has moved fast on multiple fronts.
The preservation group's lawyer sent a response letter Sunday refusing to dismiss the case. Gregory Craig, the attorney representing the National Trust, told the Justice Department that the core legal question had not changed.
Craig wrote:
"What Saturday's awful event does not change is that the Constitution and multiple federal statutes require Congress to authorize construction of a ballroom on White House grounds, and that Congress has not done so."
That argument has been the backbone of the lawsuit from the start: that the president lacks unilateral authority to build a major new structure on White House grounds without congressional approval. Judge Leon's ruling in late March sided with that reading. The appeals panel's decision to allow construction to continue has not resolved the underlying question, it merely kept the project alive pending further review.
The DOJ's counterargument is blunt. In its formal filing, the department stated that "every additional day of White House vulnerability harms the government." Blanche himself posted on X: "It's time to build the ballroom." Breitbart reported that Blanche also said the department "absolutely" believed there was "no better example of why this ballroom is necessary" than what happened Saturday night.
President Trump spoke to reporters after the shooting and connected the attack directly to the ballroom project. He said:
"I didn't want to say this but this is why we have to have all of the attributes of what we're planning at the White House. It's actually a larger room, and it's much more secure."
Trump described the planned facility as "drone proof" with "bulletproof glass." He said the Secret Service and the military were both demanding the project move forward.
The president also placed the project in a longer historical context, telling reporters: "They wanted the ballroom for 150 years for lots of different reasons but today is a little bit different because today we need levels of security that nobody has ever seen before."
The administration's broader argument is straightforward: forcing a president to attend large events at off-site venues like the Washington Hilton creates exactly the kind of security vulnerability that Saturday's shooting exposed. A hardened ballroom inside the White House perimeter would eliminate that risk. Whether the courts accept that reasoning, or whether it overrides the statutory questions Judge Leon raised, remains to be seen.
The shooting triggered a rapid response from GOP lawmakers who moved to give the ballroom explicit congressional authorization, potentially cutting the legs out from under the preservation group's core legal argument.
Colorado Rep. Lauren Boebert wrote on social media Sunday that she was drafting legislation to ensure the ballroom gets built. She added:
"I don't believe congressional approval is required for the project, but if it'll keep activist judges on the sideline, so be it. More to come this week."
Florida Rep. Randy Fine indicated he would introduce a bill titled the Build the Ballroom Act. Fine called the lawsuits against the project "nonsense" and said Saturday's events made the need clear. He challenged Democrats to cosponsor the legislation, framing it as a test of whether they would "repudiate their violent rhetoric against President Trump."
This pattern of the Justice Department taking sweeping action while congressional allies move in parallel has become a signature of the current administration's approach to contested policy fights.
Montana Sen. Tim Sheehy said he would introduce companion legislation in the Senate. Sheehy framed the issue in stark terms:
"It is an embarrassment to the strongest nation on earth that we cannot host gatherings in our nation's capital, including ones attended by our President, without the threat of violence and attempted assassinations."
Sheehy called the ballroom project "common sense." Breitbart also reported that Sens. Lindsey Graham and Rand Paul said they would introduce their own legislation to authorize the $400 million project.
The DOJ has now formally asked Judge Leon to dissolve the injunction. The preservation group has refused to back down. An appeals panel has allowed construction to continue into June, with a hearing set for June 5. And at least four members of Congress are drafting legislation to authorize the project outright.
The legal question at the center of this fight, whether the president can build a major structure on White House grounds without explicit congressional sign-off, has not been resolved. Judge Leon said no existing statute gives the president that authority. The appeals panel has not ruled on the merits. If Congress passes authorization legislation, the lawsuit's foundation could collapse regardless of what the courts decide.
The DOJ's willingness to intervene forcefully in politically charged disputes has been a defining feature of the Blanche era. This case fits the pattern: the department identified a legal obstacle, applied public pressure, set a deadline, and escalated when the other side didn't budge.
Several open questions remain. The full details of Saturday's shooting, including the extent of any injuries, have not been fully laid out. The exact scope of the appeals panel's June review is unclear. And whether the preservation group can sustain its legal position if Congress acts is an open question that could reshape the case entirely.
The Trump Justice Department has shown repeatedly that it will not wait for courts to sort things out on their own schedule when it believes the stakes are high enough.
A gunman opened fire at a Washington hotel where the president was attending dinner, and a preservation nonprofit is still in court arguing about construction permits. Sometimes the gap between what the law says and what common sense demands is wide enough to drive a ballroom through.
