Hillary Clinton has been a disaster as a senator. A disaster.

We are a debtor nation, our airports are third world, our highways are falling apart. Our roads, our bridges, everything, we're like third world.

When Secretary [Hillary] Clinton talks about this, I mean, I'll take the admirals and I'll take the generals any day over the political hacks that I see that have led our country so brilliantly over the last 10 years with their knowledge. OK? Because look at the mess that we're in.

You know who the big winner in Mosul is going to be after we eventually get it - and the only reason they did it is because she's running for office of president and they want to look tough.

Sheer persistence is the difference between success and failure.

I would need to display great restraint, but we've got to have toughness.

I think Aleppo is a disaster, humanitarian-wise.
