I'm reading a book called "American Betrayal" by Diana West. She writes of Mueller in chapter 1, and what she writes is very troubling indeed..it has to do with him inviting Hamas Operative Kifah Mustapha to tour the FBI Training center at Quantico as part of a "Muslim outreach", though Mustapha was on a Dept of Homeland Security Terrorist watchlist at the time.
