A federal appeals court is allowing President Trump to continue building his $400 million ballroom at the White House’s former East Wing, reversing a lower court’s order from the previous day that temporarily blocked the construction. Last fall, Trump tore down the East Wing to build the ballroom, prompting a lawsuit by the National Trust for Historic Preservation. Trump has said the ballroom ​would be a “shed” for ​a “massive” military ⁠complex being built underneath. Meanwhile, the Commission of Fine Arts, whose members were hand-picked by President Trump, has approved plans to build a 250-foot tall “Triumphal Arch” in Washington, D.C. The gold-adorned structure would tower over the nearby Lincoln Memorial and would dwarf other federal monuments.
