I'm not going to play pundit on Donald Trump and criticize him. I will say the media's treatment of that illustrates a very, very different - I mean, it dominated the news for a week to 10 days once he was the nominee. In the primary, it didn't get, seemingly, even 30 seconds of news.

What we saw with both Donald Trump and Marco Rubio, that their response, whenever you point to anything in their record, is just to yell, "Liar, liar, liar," and to get very personal and to make direct character attacks. And my approach, from the very beginning of this President's campaign, starting a year ago in 2015, is that I will not respond in kind. I do not intend to insult any of the candidates.

I don't think we should be engaged in nation-building. It's not our job to turn foreign nations into democratic utopias, to try to turn Iraq into Switzerland. It is the military's job to hunt down and kill our enemies, to kill ISIS before they murder American citizens and they wage jihad.

If there's not a message that people care about, they're not going to work on the campaign.

I think the establishment donor class has begun to crumble. They`re searching for [Marco] Rubio, trying to get some momentum there. But the establishment in terms of the official elected leadership of the Republican Party, when you look at [Kevin] McCarthy, they`re starting to wrap theirselves around the idea of [Donald] Trump, holding back on an endorsement.

Harry Reid employed the so-called nuclear option, broke the Senate rules to change the Senate rules, lowered the threshold for confirmation from 60 votes to 51 votes. And it is a direct result of Harry Reid that we now have the most conservative Cabinet in decades.

I'm not going to impugn anyone's integrity. I'm not going to attack their character. And, in fact, I will happily praise both Donald Trump and Marco Rubio as men who I admire, as people who I'm not going to go personal with them.
