Among the most striking things that I have learned is how much we have in common. I've sat down with people everywhere, discussing what was in their hearts and on their minds. And it doesn't take long to find commonality, which is often overlooked, ignored, dismissed, and rejected otherwise.

I voted for every sanction against Iran when I was in the Senate, but it wasn't enough. So I spent a year-and-a-half putting together a coalition that included Russia and China to impose the toughest sanctions on Iran.

I wanna do the very best job I can to fulfill the trust and faith that people have in me.

I've said this before and I'm very proud of it, that when it comes to judgment, having run a hard race against Senator [Barack] Obama at the time, he turned to me to be secretary of State. And when it comes to the biggest counterterrorism issues that we faced in this administration, namely whether or not to go after bin Laden, I was at that table, I was exercising my judgment to advise the president on what to do, on that, on Iran, on Russia on China, on a whole raft of issues.

In nearly every religion I am aware of, there is a variation of the golden rule. And even for the non-religious, it is a tenet of people who believe in humanistic principles.

I think what more and more Americans are concluding is that Donald Trump is not a man who is qualified to be president, and he is not fit to be commander and chief.

Donald [Trump] never tells you what he would do. Would he have started a war? Would he have bombed Iran? If he's going to criticize a deal that has been very successful in giving us access to Iranian facilities that we never had before, then he should tell us what his alternative would be.
