A federal panel responsible for reviewing President Donald Trump's plans to build a massive ballroom on the site of the former White House East Wing is expected to advance the project. The U.S. Commission of Fine Arts, led by appointees of the Republican president, is likely to vote on the design at its monthly meeting Thursday. At last month’s meeting, some commissioners questioned the architect about the project's “immense” design and scale even as they broadly endorsed the president’s vision for a ballroom twice the size of the White House itself.
