Shortly after taking office, Khan criticized Trump's views of Islam as ignorant -- remarks that Trump said had offended him. The new mayor had been responding to a suggestion from Trump that he would make an "exception" to his proposed "temporary Muslim ban" for Khan.
"Let's take an I.Q. test," Trump said Monday, adding that Khan had never met him and "doesn't know what I'm all about."
"I think they're very rude statements and frankly, tell him, I will remember those statements. They're very nasty statements."
