In this June 7, 2016 file photo, Republican presidential candidate Donald Trump waves at supporters as he leaves the stage with his wife Melania after a news conference at the Trump National Golf Club Westchester in Briarcliff Manor, N.Y. Melania Trump's former modeling agent says the wife of the GOP presidential nominee obtained a work visa before she modelled professionally in the U.S. in the mid-1990s. Melania Trump, the third wife of GOP presidential nominee Donald, over the weekend threatened British tabloid The Daily Mail with a libel suit after it suggested the Slovenian modeling agency she worked for in the '90s also operated as a pricey escort service.
