Why Revoke Tariq Ramadan's U.S. Visa?

He has praised the brutal Islamist policies of the Sudanese politician Hassan Al-Turabi. Mr. Turabi in turn called Mr. Ramadan the "future of Islam."
Mr. Ramadan was banned from entering France in 1996 on suspicion of having links with an Algerian Islamist who had recently initiated a terrorist campaign in Paris.
Ahmed Brahim, an Algerian indicted for Al-Qaeda activities, had "routine contacts" with Mr. Ramadan, according to a Spanish judge (Baltasar Garzón) in 1999.
Djamel Beghal, leader of a group accused of planning to attack the American embassy in Paris, stated in his 2001 trial that he had studied with Mr. Ramadan.
Along with nearly all Islamists, Mr. Ramadan has denied that there is "any certain proof" that Bin Laden was behind 9/11.
He publicly refers to the Islamist atrocities of 9/11, Bali, and Madrid as "interventions," minimizing them to the point of near-endorsement.
