The government has now moved from being a partner to a predator.

We will not abandon the people of South Sudan. They are in critical need, and they need the international community.

Imposing sanctions may very well be needed, including arms embargoes and governance issues.

I do think an arms embargo is necessary, can be effective. It is long, long, long, long overdue.

It is necessary as a signal to all the parties and to the people of South Sudan that the international community, the United States, we find this conflict utterly beyond the pale morally.

Would you send them back? Would you put them back into harm's way, incarcerated in Iran?

Today is about headlines, not headway.

I hope you understand this is a political game to try once again to, number one, trash the Obama Administration; number two, trash the Iran nuclear deal.

If this was a separate deal, cash-for-Americans, I would be agreeing with my colleagues on the other side. Ransom is unacceptable.

I think the judgment--the questioning of judgment on any settlement is a fair question.

There have been settlements that inured to the benefit of Americans totaling about $2.5 billion.
