Islamic scholar Tariq Ramadan has announced his resignation at the University of Notre Dame after failing to obtain a visa to enter the United State. The State Department has yet to tell Ramadan or Notre Dame why Ramadan’s visa was rejected claiming the decision is classified. But the government has admitted his visa was denied under a section of US law that bars terrorists and their associates. Ramadan is well-regarded in intellectual circles as a scholar who seeks to bridge the Western and Muslim worlds. The Washington Post reports he has drawn criticism from some Muslims that he is not Muslim enough and from some Westerners that he is insufficiently Western.
