Admission to U.S. Denied. Tariq Ramadan was denied admission into the United States because he had made a donation to a charity that had supplied funds to Hamas and that such contributions were "material support" to a terrorist organization (the charity). The Second Circuit vacated and remanded the decision of the District Court, holding that the record was not clear whether the consular officer had confronted Ramadan with the allegations against him and afford him the opportunity to prove by clear and convincing evidence that he did not know (and reasonabley should not have known) that the recipient of his contributions was a terrorist organization.
