A divided Supreme Court on Monday allowed the White House to continue construction on a $400 million ballroom project as lawsuits play out, a win for President Donald Trump as he flexes unprecedented executive power and remakes the capital in his image.

Trump wrote on his Truth Social platform, “I am pleased to report that the United States Supreme Court has just ruled in favor of the Ballroom/Military Complex being built without any further contingency, doubt, or threat.”

The apparent 5-4 decision replaces a temporary order issued earlier this month, shortly before a court-ordered halt would have gone into effect.

That temporary order was signed by Chief Justice John Roberts, assigned to handle appeals from the capital. But he publicly disagreed with the latest decision, writing a strong dissent that referenced the nation’s history and said the project is likely unlawful because it hasn’t been approved by Congress.

“Today’s decision is no victory for the separation of powers.” Roberts wrote. The court’s three liberal-leaning justices agreed.

The majority, on the other hand, found the National Trust for Historic Preservation likely did not have the legal right to challenge the project.

The unsigned order pointed to government arguments that the ballroom would address national security concerns by shielding a planned underground military installation and offering a more secure structure for large events than the tents currently used.

By contrast, “the only harm the Trust claims is the offense one of its members will suffer from having to view a structure of the ‘scale,’ ‘height,’ and ‘massing’ the government intends,” it states.
