The approximately $200 million project will be funded by President Trump and other private donors, White House spokesperson Karoline Leavitt said.

Construction will begin in September on a $200 million, 90,000-square-foot ballroom, his press secretary announced Thursday, fulfilling a 15-year ambition by the president to construct an event space on the White House grounds that expands the building’s entertaining capacity — but also resembles the gilded spaces of his private clubs.

Officials said a 90,000-square-foot addition to the East Wing would cost $200 million and be paid for by President Trump and other donors.
