Donald Trump is willing to make an exception to his proposed “total and complete” ban on Muslims entering the United States: the newly elected mayor of London, Sadiq Khan. But the London-born son of Pakistani immigrants had his own choice words for the presumptive Republican nominee on Tuesday.

In an interview with The New York Times, Trump said he was “happy” to see Khan elected, and that “there will always be exceptions” to his proposed ban. However, in response, Khan, called Trump “ignorant.”

In a statement to the Associated Press, he says:

“This isn't just about me—it’s about my friends, my family and everyone who comes from a background similar to mine, anywhere in the world. Donald Trump’s ignorant view of Islam could make both our countries less safe—it risks alienating mainstream Muslims around the world and plays into the hands of the extremists.”

Khan is the first Muslim elected as mayor of a Western capital city. In an interview with the BBC, he said he’s supporting Hillary Clinton in the U.S. presidential race. Clinton is the Democratic front-runner despite a stronger-than-expected showing from Bernie Sanders, the U.S. senator from Vermont.
