[Michael Flynn is] someone who has advocated for a much tighter ties with Russia and had raised some eyebrows in terms of some of the consorting that he did around Washington.

I think Donald Trump now thinks it`s time for Jeff Sessions to resign. There was a reporting that suggested that when Trump first voiced his exasperation with Sessions, that Sessions made it clear to Trump that if Trump wanted his resignation, he would offer it. It seems to me now Trump is sending a pretty clear signal that what he wants is Jeff Sessions to resign, and it`s also pretty clear to me he`s now at war with everyone in the world of justice and law enforcement in the administration.

In the national security establishment, it is somewhat frowned upon for people to take extremely harsh partisan roles in campaigns.

To get some of the substance of why [Michael] Flynn [is Defense Adviser] is so controversial.

This is a guy [Michael Flynn] who stood up at the Republican convention and reveled in the chants of "lock her up" about Hillary Clinton.

I think we should always listen to Bill Clinton about everything. And so, if that's his view then that should be the rule of law.

[Dinner with Vladimir Putin has] raised a lot of eyebrows among national security officials who looked at [Michael Flynn] and thought these kind of behaviors were not what they had thought what he was like previously.
