Judge orders Trump administration to halt White House ballroom construction unless Congress OKs it

Leon, who was nominated to the bench by Republican President George W. Bush, concluded that the National Trust for Historic Preservation is likely to succeed on the merits of its claims because "no statute comes close to giving the President the authority he claims to have."

"The President of the United States is the steward of the White House for future generations of First Families. He is not, however, the owner!" the judge wrote.

Leon suspended enforcement of his order for 14 days, acknowledging that the case "raises novel and weighty issues, that halting an ongoing construction project "may raise logistical issues." He also recognized that the administration is likely to appeal his decision.

The judge ruled that any construction work that's necessary to ensure the safety and security of the White House is exempt from the scope of the injunction. Leon said he reviewed material that the government privately submitted to him before concluding that halting construction wouldn't jeopardize national security.

Trump, in a social media post, criticized the trust for suing him over a project that he said is being built at no cost to taxpayers. "Doesn't make much sense, does it?" he wrote.

The White House did not immediately respond to a request for comment on the ruling.

The preservationists sued to obtain an order pausing the ballroom project until it undergoes multiple independent reviews and receives congressional approval.

The White House announced the ballroom project over the summer. By late October, Trump had demolished the East Wing to make way for a ballroom that he said would fit 999 people. The White House said private donations, including from Trump himself, would pay for the planned construction of a 90,000-square-foot (8,400-square-meter) ballroom.

Trump proceeded with the project before seeking input from a pair of federal review panels, the National Capital Planning Commission and the Commission of Fine Arts. Trump has stocked both commissions with allies.

The trust sued in December. On Feb. 26, Leon rejected the preservationist group's initial bid to temporarily halt the ballroom's construction. He said the privately funded group had based its challenge on a "ragtag group" of legal theories and would have a better chance of success if it amended the lawsuit, which it did.

Leon said the ballroom plans are in the final stages of the design approval process. The administration has said above-ground construction on the ballroom would begin in April.

"We are two weeks away," plaintiffs' attorney Thaddeus Heuer said during a March 17 hearing. "The imminence is now imminent."

During the hearing, Leon sounded skeptical of what he referred to as the government's "shifting theories and shifting dynamics" for its arguments in the case.

"I don't think it's a new theory," Justice Department attorney Jacob Roth told the judge.

Leon expressed frustration at Roth's attempts to equate the massive ballroom project with relatively modest construction work at the White House under previous administrations.

"This is an iconic symbol of this nation," the judge said.

The administration argued that other presidents didn't need congressional approval for previous White House renovation projects, large and small.

"Many of those projects were highly controversial in their time yet have since become accepted — even beloved — parts of the White House," government attorneys wrote.

Leon rejected the administration's claim that Congress gave the president virtually unilateral authority to construct anything on federal land in Washington, regardless of the funding source.

"This clearly is not how Congress and former Presidents have managed the White House for centuries, and this Court will not be the first to hold that Congress has ceded its powers in such a significant fashion!" the judge wrote.
