Donald Trump can't beat Hillary Clinton, I think it's very clear, and she doesn't want to run against me, because I can beat her, because I will fight her and force her to fight on ground that she will lose on.

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.
