WASHINGTON (AP) — A federal judge who halted construction of President Donald Trump’s $400 million White House ballroom clarified on Thursday that the administration can proceed with below-ground construction of a bunker and other “national security facilities” at the site.

U.S. District Judge Richard Leon in Washington issued his latest ruling in a lawsuit over the ballroom project several days after an appeals court instructed him to reconsider the possible national security implications of stopping construction.

Government lawyers had argued that the project includes critical security features to guard against a range of possible threats, such as drones, ballistic missiles and biohazards.

Leon had barred work from proceeding without congressional approval, but he suspended enforcement of that order for two weeks. The appeals court extended that stay until Friday.

Leon, who was nominated to the bench by Republican President George W. Bush, said he is ordering a stop only to above-ground construction of the planned ballroom, apart from any work needed to cover or secure that part of the project. Otherwise, the Trump administration is free to proceed with construction of any excavations, bunkers, military installations, and medical facilities below the ballroom.

“Defendants argue that the entire ballroom construction project, from tip to tail, falls within the safety-and-security exception and therefore may proceed unabated,” the judge wrote. “That is neither a reasonable nor a correct reading of my Order!”
