I was very disappointed to hear the comments of the Chief of Staff. We don't do this all the time, OK? We don't use the power and prestige of America to beat on people for political purposes.

I think our country is built on speaking your mind and having freedom of expression.

It's not a good thing. And you're on to something here that we should not be beating on a foreign country for political gain but should be for advancing United States strategic interests.

It's also confusing to me to have rough amateur diplomats out there conducting parallel diplomacy when we have professional diplomats doing their job in the Ukraine.

I think it's fine to have the inquiry. I haven't heard anything yet that would tell me that we should impeach the president of the United States.

No, that's where the rub comes in. The rub comes in that we have professional diplomats trying to do their job to root out corruption, and then we have Giuliani parachuting in, talking about corruption but maybe representing his customers.

This isn't of an etch-a-sketch. You can't go and revise what you want in the cameras and say, oh, actually, I meant the opposite.

I really think mitigation of greenhouse gas emissions is the only answer there.

I do think that the course that these countries are on is not sustainable, socially or politically.

Yes. We have done construction work all over that area, and our motto is never contract with the government.

The working group of Central American leaders... identified corruption as one of the core problems facing the region.
