I think Donald Trump's history has shown that this was a very problematic thing. There were so many ways Iraq could have gone awry once we started, and I don't think most of us spend enough time considering the dangers.

Bin Laden, who was in his country, attacked and damaged our Pentagon, and killed our soldiers right out here at the Pentagon. But his pentagon no longer exists. It is rubble.

I never had meetings with Russian operatives or Russian intermediaries about the [Donald] Trump campaign.

When you suveil a person abroad, you don't have to have a warrant to do so. That has never been so they don't have the fourth amendment protection.

More taxes, more regulation, more Washington domination, more debt. Those things are not the future for America. They will never work.

I would acknowledge that [Paul] Ryan has some really good ideas about things, and I think they'll get together, like taxes. Larry Kudlow, Stephen Moore, they've been supportive of Ryan's tax view and now they're very supportive of [Donald] Trump's. So I think that's got potential.

Good people don't smoke marijuana.
