Sadiq Khan, the first Muslim mayor of London, slams Donald Trump who recently said that he is exempting him from his proposed ban on Muslims to enter the United States.

"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 said, according to CNN.

To recall, Trump proposed "a total and complete" travel ban on foreign Muslims to visit America "until our country's representatives can figure out what the hell is going on," NBC News reported. But when Khan won the elections last week in London, Trump said that "there will always be exceptions." He also expressed that he was happy to see Khan being elected into the position and hopes that he will do a great job.

Khan rejected this suggestion saying, "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 and those around him think that western liberal values are incompatible with mainstream Islam -- London has proved him wrong," he added.

Trump proposed the ban of Muslims on America’s borders following the deadly attack in San Bernardino last December, wherein a husband and wife tandem swore loyalty to the Islamic State of Iraq and the Levant (Isil) prior the attack, The Telegraph reported. Despite international outcry and a half-a-million signed online petition to oppose the ban, and barring Trump to enter UK in response, Trump is still firm on his suggestion.

Meanwhile, Khan who is supporting Democratic candidate Hillary Clinton, is making plans to visit the US before the elections to visit mayors Bill de Blasio and Rahm Emanuel of New York and Chicago, respectively.

“Clearly [I’ll visit] before January in case Donald Trump wins,” he said in an interview with Time magazine. “If Donald Trump becomes the president I’ll be stopped from going there by virtue of my faith, which means I can’t engage with American mayors and swap ideas.”
