On April 16, in his most recent opinion in the ongoing litigation over the construction of the White House ballroom, Judge Leon of the federal district court in DC wrote: “The fact that the ballroom is planned to include security features such as bullet-proof windows and a drone-proof roof does not bring the structure within the scope of the [national security] exception. While these features may well be beneficial, Defendants have not provided any national security justification for why these features must be installed immediately such that they should be excluded from the scope of the injunction.”
