[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.

There are very diminishingly few United States senators who you would like always want to have dinner with. It used to be in the Senate there were an awful lot of them. There are very few of them today that you would just be dying to go out and have dinner with. John McCain is someone I`d have dinner with seven nights a week.

Donald Trump is now at war with Jeff Sessions. He`s now at war with James Comey. He`s at war with Andrew McCabe, and he`s at war with Robert Mueller. He`s attacked all of those people in this New York Times extraordinary interview. And I`ll just remind people that the last time Donald Trump went to war with an establishment, that was the intelligence establishment, he started that back in December 2016 , that did not work out for him well.

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.

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

[Michael Flynn] become someone who for a lot of his former colleagues, people like Stanley McChrystal who looked at General Flynn and sort of said, this is not the person I thought I knew.

[Michael Flynn] has called President [Barack] Obama a liar.
