A lightning rod in discussions of Muslim identity in both Europe and the United States, Swiss-born scholar Tariq Ramadan has returned to the United States for a series of lectures. His visa was formerly revoked by the State Department in February of 2004.

Ramadan says he was kept out because of "The fact that I was very critical about the US's foreign policy." Critics claimed he donated to a Hamas-linked charity, and those were the grounds the Bush State Department banned him under, though the charity wasn't officially associated with terror by the US until after Ramadan donated to it. Now, under a new administration, Hillary Clinton has formally lifted the ban on Ramadan's travel to the United States.
