Khizr Khan Event In Toronto Cancelled Over Travel Privileges Review, Says Organizer

TORONTO — The organizer of a luncheon featuring a speech by the father of an American Muslim soldier killed in Iraq says the event has been cancelled because the man's "travel privileges are being reviewed.''

Ramsay Talks says Khizr Khan, who has publicly criticized U.S. President Donald Trump for his anti-Muslim rhetoric, was scheduled to be in Toronto on Tuesday to talk about tolerance, understanding and unity.

Khan is a Harvard-trained lawyer who immigrated to the United States from Pakistan decades ago.

"This turn of events is not just of deep concern to me but to all my fellow Americans who cherish our freedom to travel abroad," Khan said in the statement.

"I have not been given any reason as to why. I am grateful for your support and look forward to visiting Toronto in the near future."

The company says Khan was notified late Sunday night that his travel privileges were being reviewed.

Neither Khan nor Ramsay Talks say who is reviewing his travel privileges and why. Khan and his wife are U.S. citizens.

Ramsay Talks had listed the event with Khan on its website, but Monday afternoon, the site appeared to be down.

On Monday, Trump unveiled a revised travel ban that temporarily halts entry to the U.S. for people from six Muslim-majority nations who are seeking new visas and suspends the country's refugee program.
