The US Supreme Court allowed the Trump administration to continue construction of a $400 million White House ballroom project on 2026-09-01 while lawsuits over the project proceed. ^[1] The Supreme Court of the United States ruled with a 5-4 majority to grant a temporary stay, allowing the construction of the ballroom to continue pending the main trial. ^[2] Chief Justice John Roberts issued a temporary order hours before a lower-court decision would have halted the work, but the Supreme Court replaced this order. ^[3] Chief Justice John Roberts publicly dissented from the latest order, joining three liberal-leaning justices who called the construction likely unlawful. ^[4] The Supreme Court majority did not decide the legality of the project but found that a preservation group likely did not have the legal right to challenge it. ^[5] An appeals court had previously ordered a construction stoppage, ruling that President Trump cannot build the ballroom unilaterally and must obtain approval from the US Congress. ^[6] US President Donald Trump stated on Truth Social that he is preparing for a long and hard legal battle regarding his planned White House ballroom. ^[7]
