Link is to a video compilation of foxnews reports about Israeli spying. Specifically, their involvement and foreknowledge of 9/11. Mueller was head of the FBI at the time, and shut down further investigations into these inquiries. Mueller also blocked the families of 9/11 from suing Saudi Arabia. The reason?
