The National Trust for Historic Preservation has filed a request with the Supreme Court to pause construction of Donald Trump's White House ballroom, citing concerns that the project, currently 65% complete, could become irreversible.

The group emphasized that the administration's admission that the project is 'on the brink of a fait accompli' underscores the urgency of their request.

Lawyers for the trust accused the Trump administration of attempting to 'outrun judicial review' and failing to secure necessary congressional approval for the $400 million project.

US District Judge Richard Leon previously ruled that 'no statute comes close to giving the president the authority he claims to have,' reinforcing the trust's position.

The appeals court has upheld an order to pause above-ground construction, which the administration is contesting.

Chief Justice John Roberts has set a deadline for the trust to respond to the administration's petition, as the legal battle continues over the future of the ballroom.

The National Trust argues that the current state of the project, described as an open construction site, complicates efforts to protect the historic integrity of the White House.

The trust's attorneys maintain that the preliminary injunction is 'already narrowly tailored, and limited in scope and duration,' indicating a focused approach to the legal challenges at hand.
