Secretary of State Marco Rubio on Iran: We are postured in the region for one simple reason, and that is that we understand that there could be threats to our forces in the region.

We’ve seen them be threatened in the past, and we want to make sure that we have sufficient capacity to defend them if, God forbid, that were to happen.

We are focused on negotiations. If that changes, it’ll be obvious to everyone, and obviously whatever the law requires us to do, we’ll do.
