Khan also took aim at the U.S. president for emboldening racists to speak out from the fringes of society.

“These people have been inspired by mainstream politicians who subscribe to their point of view,” Khan said. Trump “is a guy who amplifies racist tweets; amplifies the tweets of fascists; says things that are deeply objectionable.
