A divided Supreme Court has ruled that construction on a White House ballroom can proceed. The decision was made with a 5-4 vote, lifting a block on above-ground work. President Trump has stated that the project is necessary for national security.

The ruling overturns a lower court decision that would have restricted construction until Congress provided additional approvals. The Supreme Court's conservative justices, including President Trump's appointees, sided with the administration.

Further details on the ruling and its implications are available from the source. The decision allows the construction project to continue, but the specifics of the project and its timeline have not been outlined in the available information.
