As fears grow over Iran secretly developing nuclear weapons, U.S. counterintelligence officials are keeping a close eye on scientists from Iran and other Muslim nations working at the U.S. nuclear weapons laboratories, WND has learned. The Energy Department recently revoked the security clearance of an Egyptian-born nuclear physicist because he was suspected of "conflicting allegiances." Last year, DOE and FBI agents began questioning Moniem El-Ganayni, who worked on the side as a Muslim prison chaplain.
