President Donald Trump has defended the $400 million ballroom he is building for the White House, stating that it is a military component that was supposed to remain secret. This explanation came as he unveiled architectural drawings of the 90,000-square-foot ballroom, which critics have said is out of scale to the rest of the building. The National Trust for Historic Preservation is fighting the ballroom in federal court for allegedly building without required approvals or congressional authorization. The president has argued that the ball room has been needed for 150 years due to the size of the East Room, which he claims holds only 125 people for formal dinners.
