The Obama administration said Monday it had turned down Donald Trump's offer to pay for a new $100 million White House ballroom, USA Today reports. "I'm (not) sure it would be appropriate to have a shiny gold 'Trump' sign on any part of the White House," says Press Secretary Josh Earnest. "That's what most of the buildings that he offers to build include." For his part, Trump said at a rally in Sioux City that a ballroom would be better than tents on the lawn for visiting dignitaries. "No. 1, it’s not a good security thing. No 2, the guy that owns the tents is making a fortune," he says. Trump had suggested the ballroom idea before but never heard back from the White House. "He did offer to build one," David Axelrod tells Time. "I passed his offer along to the social secretary." (More Donald Trump stories.)
