Interview 7/14/06: Regarding 9/11 "There is no question in my mind, that there is enough evidence to justify a very comprehensive and hard hitting investigation of the kind we have not seen. With subpoenas, general questioning of people, releasing a lot of documents. There’s no question that very serious questions have been raised about how much they knew before hand and how much involvement there may have been." http://www.infowars
