Frank Gaffney is founder of conservative think tank the Center for Security Policy, which released a 177-page report on Islamic law's threat to America. He served as Deputy Assistant Secretary of Defense for Nuclear Forces and Arms Control Policy during the Reagan administration, as well as a short stint as Assistant Secretary of Defense for International Security Policy before his appointment was blocked by the Senate.
Since 9/11, Gaffney has accused many public officials and organizations of terrorist ties. Among his accusations, he has stated that both President Obama's nomination of Elena Kagan to the Supreme Court and banks' accommodations of non-interest financing are parts of a secret ploy to institute Islamic law in the U.S. Gaffney's insistence that sharia is a widespread threat to the United States is stated well in a piece he wrote for The Washington Times: "Most mosques in the United States are actually engaged in—or at least supportive of—a totalitarian, seditious agenda they call Sharia. Its express purpose is undermining and ultimately forcibly replacing the U.S. government and its founding documents."
When U.S. Army General David Petraeus condemned the burning of Qurans by Pastor Terry Jones of Dove World Outreach Center in Florida, Gaffney accused Petraeus of submitting to sharia law. Regarding the proposed Park51 center ('Ground Zero mosque'), Gaffney said it was, "a durable, symbolic taunt by our enemies about their bloody victory."
Among Gaffney's critics is Republican lobbyist Grover Norquist who has said in response to Gaffney's statements, "When you say we're going to start telling people you can't build a church, a synagogue, or a mosque somewhere, that's a direct attack on religious liberty."
