I didn't say I would cut off all communication with [Vladimir] Putin. What I said was as president of the United States, now is not the time to talk with him.

Hillary Clinton failed to mention that her agreement with a precipitous withdrawal and declaration of victory in 2011 helped left swaths of territory and weaponry from ISIS. She failed to mention that she described Bashar al-Assad as a positive reformer and opened an American embassy. She failed to mention a complete failure strategy in Libya, which now is enabling ISIS to move into Libya.

To wage war, we need a commander in chief who has made tough calls in tough times and stood up to be held accountable over and over, not first-term senators who've never made an executive decision in their life.

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.

Unlike Hillary Clinton, I am not afraid to answer questions about my track record or my accomplishments or my principles.

So what will define greatness for your generation? I believe it is to use the knowledge that you have earned here to find ways, not only to connect to computers, but to connect to people; not only to bridge gaps in science, but to bridge gaps between cultures; not only to use numbers and formulas to create, but to use words to lead, and in the process, to close that canyon between ignorance and understanding.

Look, you need technical skills to run a company.
