Foreign aid is not something the vast majority of Americans support, but definitely not conservatives.

I've heard of many tragic cases of walking, talking normal children who wound up with profound mental disorders after vaccines.

The one way, possibly, out of this is for [Bashar] Assad to abdicate and plead, perhaps to Russia or somewhere else. Would save another wave of civilian casualties if we could get him to abdicate.

I think we're never fully protected, but I think we need to do everything we can to stop threats to us.

I think that if you believe in regime change, you're mistaken. In 2013, we put 600 tons of weapons - us, Saudi Arabia, and Qatar - into the war against [Bashar] Assad. By pushing Assad back, we did create a safe space.

In a reality, what we should be doing is having quiet diplomacy with the Russians to convince them that it's in their self-interest to have a more stable Middle East because trade enriches us all.

Our intervention to destabilize the Assad regime has really made the chaos worse in Syria. And if you were to get rid of Assad today, I would actually worry about the 2 million Christians that are protected by Assad.
