Donald Trump boasted his planned White House grand ballroom will dwarf Windsor Castle's banquet hall, making the jaw-dropping claim during a UK state visit, Wonderwall.com can reveal. The president made the brag during a September 2025 trip to England, where rolled out a lavish state dinner in his honor, just one month before Trump sparked outrage by ordering the White House's East Wing torn down to kick off construction on the mega-ballroom. 'My Ballroom Is Going to be Bigger' Trump spoke to more than 600 guests in Windsor Castle's St George's Hall at the UK state dinner in 2025.
