Jane Harman: “As I have often said, the terrorists won't check our party registration before they blow us up.”

The American people deserve a voice in this. They have to understand what the trade-offs are in terms of resources and loss of life.

I think we should be very, very careful, given the Iraq experience, and if the people of Iran who elected their government by more than 50 percent in a four-way field want to change their government, then let them do that.

I think that if President Trump can reach a strong deal with the North Koreans he will deserve enormous credit.

Should it have addressed Iran's other malign behavior? Yes, it should, and it still could, if this side agreement were entered into.
