I think bolstering free trade is a boon to the dollar.

I will not speak to Vladimir Putin personally until we've rebuilt the 6th Fleet a little bit right under his nose; rebuilt the missile defense program in Poland right under his nose; and conducted a few military exercises in the Baltic states.

When we miss with all the metadata collection we've had, the San Bernardino couple and the Tsarnaev brothers, what that suggests to me is that we are using the wrong algorithms to search through all this data.

Some of this is bureaucratic ineptitude and a great deal of this is an administration that doesn't understand the urgency of the situation, and therefore this [Barack Obama] administration has not reached out actively to the private sector and said, we need help.

When America does not lead, the world is a dangerous and a tragic place. This is a bad deal. [Barack] Obama broke every rule of negotiation.Yes, our allies are not perfect, but Iran is at the heart of most of the evil that is going on in the Middle East through their proxy.

Nobody needs to worry about my toughness.

[Hillary] Clinton, we are not where we need to be in the fight against ISIS.
