The FBI has confirmed that a Chicago Muslim cleric with long ties to terrorist groups Hamas and the Muslim Brotherhood was part of a group given a tour of the National Counterterrorism Center and FBI headquarters, the Washington Times reported.

Kifah Mustapha, imam of the Mosque Foundation in Bridgeview, Ill., was named as an unindicted co-conspirator in a Hamas funding trial and was a longtime associate of leaders of the Holy Land Foundation, which was shut down by the government in 2001. Five Holy Land officials were convicted in 2008 of giving more than $12 million to Hamas.

FBI leaders allowed Mustapha in the six-week training program at the FBI's Quantico, Va., facility, because they didn't consider him a security risk, said FBI Chicago spokesman Ross Rice. "If we thought he was a security risk, we wouldn't have included him," Rice said.

Earlier this year, the Illinois State Police rescinded an invitation to Mustapha after the Investigative Project on Terrorism published a report outlining his ties to HLF and Hamas.
