I'm deeply concerned. And I think, in many ways, the Trump presidency poses a clear and present danger to our country and to the world.

Together let's defend the shared values that already make America and Israel great.

I'm going to stand up for what [Donald Trump] says and does that is threatening to Americans, to the lives of Americans, the rights of Americans.

That is the number-one threat we face in the world. And it becomes particularly threatening if terrorists ever get their hands on any nuclear material. So a man who can be provoked by a tweet should not have his fingers anywhere near the nuclear codes, as far as I think anyone with any sense about this should be concerned.

I think what President [Barack] Obama has done is to chart a steady course. When I was there, the first four years we had a lot of cleanup to do. We inherited a lot of bad feelings from the [George W.] Bush administration, and much of what I spent my time doing was traveling around the world reassuring friends and allies.

Donald Trump bigotry, his bluster, his bullying, have become his campaign.

I call it [Donald's Trump plan] trumped-up trickle-down, because that's exactly what it would be. That is not how we grow the economy.
