I don't know about you, Anderson, but do you have the sense that the president is becoming more irrational in his tweeting and sort of like -- busting loose whenever he can?

What we should be doing is rallying to and unifying the western nations in the fight against terrorism.

It has badly hurt the U.S. relationship with NATO.

All indications and everybody inside has been telling us it's chaotic.

For the president to come in this way only weakens his case.

This president really does not listen to the people around him.

It would be a terrible mistake politically to invoke executive privilege here and it would be challenged legally.

It is not a good one to me. In years past -- we've been told -- well, because, look, I think with some 70 years ago, this country came to the aid of many others, especially in Europe, with a marshal plan and we saw that as one of the…

If things are bogged down, you can't blame Mueller and the investigation, nor even the leaks, frankly.

I just don't think you can sweep this away as objectionable as the leaks may be. I mean, the fact is, we have rarely in the last 40 years had criminal investigations that go right into the heart of the White House.

President Trump is going to be very furious at this news. First of all, he thinks there's nothing to it, of course, but secondly, the fact that it was leaked out there.

He bears some responsibility as president for making this happen.

Executive privilege will not extend back to the transition and to the campaign.

It's about more than collusion. It is increasingly about follow the money.

He could invoke executive privilege.

I don't think the obstruction issue is going to be settled in the court, it's much more likely to be settled in the court of public opinion especially in the elections of 2018.

I think it's indisputable that the president wanted this investigation to go away, that he's found it very burdensome.

I think that it suggests -- I argued here the other night, we're in impeachment territory and now we know that the White House lawyers are investigating how impeachments take place even though they think it's down the road.

Suggests the reason -- And I think I've been told this before, that Pres. Obama warned off incoming Pres. Trump about hiring him.

The pattern here is the president goes to Comey, the FBI director and says I need your loyalty. Comey refuses to give it to him. Then a subsequent meeting according to these reports from Comey, the president pressures him to let the Flynn…

I have political pressure coming on me about these investigations. This thing is something I don't want. I want to get rid of it and I fired the son of a gun.

I think we're in impeachment territory now for the first time.

The evidence is piling up that the president was particularly anxious to protect General Flynn.

Obstruction of justice was the number one charge against Nixon, that brought him down.

I think we are in impeachment territory for the first time.
