WASHINGTON (AP) — President Donald Trump’s White House ballroom is expected to win approval from a key agency on Thursday, days after a federal judge ordered a halt to construction unless Congress allows what would be the biggest structural change to the American landmark in more than 70 years.

The National Capital Planning Commission, the agency tasked with approving construction on federal property in the Washington region, is going ahead with the vote because U.S. District Judge Richard Leon’s ruling on Tuesday affects construction activities, not the planning process, commission spokesperson Stephen Staudigl said.

But despite the agency’s expected approval, the judge’s ruling and the legal fight over the ballroom could stall progress on a legacy project that Trump is racing to see completed before the end of his term in early 2029. It’s among a series of changes the Republican president is planning for the nation’s capital to leave his lasting imprint while he’s still in office.

The vote by the 12-person commission, including three members appointed by Trump, had initially been scheduled for March but was pushed to Thursday because so many people signed up to comment on it at the commission’s meeting. The comments were overwhelmingly opposed to the ballroom.
