In other news, the American Civil Liberties Union has filed a lawsuit on behalf of Tariq Ramadan — the Muslim scholar barred from the US under the USA Patriot Act. In 2004, Ramadan, a Swiss professor known for his work on Islamic theology and the place of Muslims in the modern world, was appointed to teach Islamic philosophy and ethics at the University of Notre Dame. But just days before he was set to travel, his visa was revoked without explanation at the behest of the Department of Homeland Security. Ramadan was barred under a section of the Patriot Act, which bars entry to foreigners who have used a “position of prominence … to endorse or espouse terrorist activity.” The ACLU is seeking to strike down that clause.
