Khan has been a strident opponent of President Trump since Trump rose to prominence during the 2016 Presidential election. Khan frequently criticizes the President's rhetoric towards Islam.
"I’m really keen for Donald Trump to come to London, because Donald Trump, it appears to me, is under the impression that western liberal values are incompatible with mainstream Islam," Khan said last year. "I want him to come to London to meet Londoners of Islamic faith who love being British, love being a Londoner, love being a Muslim."
Mr. Khan may say that, but his record, which includes addressing gender-segregated audiences and promising to ban "unrealistic" images of scantily clad women from ads on public transport, seems to indicate otherwise. Khan also served as a lawyer for the Nation of Islam in its successful High Court bid to overturn the 15-year-ban on its anti-Semitic leader, Louis Farrakhan.
Just one decade ago, Khan visited terrorist Babar Ahmad in Woodhill Prison before he was extradited to the U.S. in 2012. Ahmed plead guilty to conspiracy, and providing material support to the Taliban.
