According to the SITE Institute:
"A U.S.-based Islamic charity received millions of dollars in State Department funds for charitable work in Africa-at the same time that its overseas affiliates were allegedly funneling large sums of money directly to Osama bin Laden, according to newly released government documents. The new information about the Islamic American Relief Agency, and its parent organization in the Sudan, appears to represent the strongest evidence yet that, at least for several years in the late 1990s, U.S. taxpayer money may have been inadvertently used to finance the terrorist operations of Al Qaeda."
