U.S. President Donald Trump has announced a $200 million project to build a new 90,000-square-foot ballroom in the East Wing of the White House. Privately funded by Trump and several unnamed American donors, the project will begin in September. The ballroom will seat 650 guests, replacing the need for temporary tents during state events. Trump said no public funds will be used. The White House described it as a significant and elegant upgrade for hosting official functions.
