Nobody needs to worry whether or not I've been tested.

Hillary Clinton has gotten every foreign policy challenge wrong.

We [the Republicans] help the middle class when we unburden them from the very policies that Hillary Clinton would double down on. She champions Big Government, which we know enables crony capitalism and exacerbates inequality. If you are wealthy, powerful and well-connected, you can handle Big Government.

The pace of change is so great, there is always something else going on. What that says to me is that you have to have strategic vision and peripheral vision. Strategic vision is the ability to look ahead and peripheral vision is the ability to look around, and both are important.

Silicon Valley companies need to be asked to bring the best and brightest, the most recent technology to the table. I was asked as a CEO. I complied happily. And they will as well. But they have not been asked. That's why it cost billions of dollars to build an [Barack] Obama website that failed because the private sector wasn't asked.
