I think there's a good chance we would have prevented at least a part of 9/11. In other words, there were four planes. There were almost 20 — 19 pers… - Robert Mueller

Second) the Justice Department has asserted privileges concerning investigative information and decisions, ongoing matters within the Justice Department, and deliberations within our office. These are Justice Department privileges that I will respect.
The department has released a letter discussing the restrictions on my testimony. I therefore will not be able to answer questions about certain areas... of public interest. For example, I am unable to address questions about the opening of the FBI's Russia investigation, which occurred months before my appointment, or matters related to the... Steele dossier. These matters are the subject of ongoing review by the department. Any questions on these topics should therefore be directed to the FBI, or the Justice Department.

Cyberbullying, I know, it's being handled, generally, on the state side with state legislation. I look at it, frankly, as a father with children, with their ability to use Facebook and the like, knowing that anything you put on Facebook is going to be there and be there and be there.

I think we're certainly vulnerable when it comes to the type of information that is out there. The type of information that is out there and available to those that want to find it and want to damage and harm to us. We're also to a certain extent vulnerable by the fact that we live by the rules passed by Congress. If I want to get an application before the court to intercept somebody's conversations, I have to show probable cause to believe that person is affiliated with a terrorist group. And if I don't get the probable cause, I can't do it. And we've had instances, Awlaki, a relatively famous individual exporter of the type of terrorism we've seen in the United States, was doing videos for a substantial period of time before the Fort Hood shooting, and it was only after that that we found out he was involved in the operations. Any other country, they may well have been up on his wire beforehand, because there's no responsibility of showing a court that there's probable cause to believe that this individual is involved in terrorist activities.
