As president, I will stand up to the great human rights tests of our time - in China, Russia, and the Middle East. We must send a signal to our allies and adversaries that America is back in the leadership business.

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.

What is really disappointing about this president is not just lack of leadership, but his tendency to always place the blame for his lack of leadership somewhere else

Do not be afraid to make decisions, do not be afraid to make mistakes.

Look, I'm a cancer survivor, all right? So I have great personal empathy for people who have pre-existing conditions and can't get insurance.

You can find lots of people like you through technology, and women in particular like communities.

Human potential is the only limitless resource we have in this world.
