Khan and Trump have clashed publicly since the latter was elected. Khan was highly critical of Trump’s travel ban and then last spring, Trump berated (and misconstrued) Khan following the London terrorist attack that saw several killed and dozens injured. Khan vowed at the time that he wasn’t “tangoing with this guy. I’ve got better things to do.”

But he also told Channel4 News that a state visit by the U.S. President should be cancelled. “I don’t think we should be rolling out the red carpet to the President of the USA in the circumstances where his policies go against everything we stand for,” Khan said in June 2017.

In November, after POTUS’ retweets of anti-Muslim messages put out by the UK’s far-right Britain First party, Khan said he had called on Prime Minister Theresa May “to cancel her ill-judged offer of a state visit” and added, “It is increasingly clear that any official visit at all from President Trump to Britain would not be welcomed.” – Deadline
