We have to stick up for ourselves as people and we have to stick up for our country when we're being mistreated, remember that.

My administration will put new American metal into the spine of this nation.

One of my first directives, after taking office, will be asking the Joint Chiefs of Staff and all relevant federal departments to conduct a thorough review of United States cyber defenses and identify all vulnerabilities - and we have to do that immediately - including to our power grid, our communications system, and all vital infrastructure.

Another reform, involves new screening tests for all applicants that include, and this is so important, especially if you get the right people. And we will get the right people.

Republicans and Democrats agree that this should be done, $2.5 trillion. I happen to think it's double that. It's probably $5 trillion that we can't bring into our country.

I think it's very sad, when you look at Barack Obama, as an example, lands Air Force One in China, and they don't want to put out stairs to get off the plane. And he has to use the stairs that mechanics use to get up and down to fix the plane. They wouldn't give him stairs.

If I decide to run for office, I will release my tax returns. Absolutely. I would love to do that.
