I delivered a clear and forceful message that although we recognize Russia's intelligence gathering will sometimes take place even if we don't like it, there's a difference between that than either meddling with elections or going after private organizations or commercial entities, and that we're monitoring it carefully, and we will respond appropriately if and when we see this happening.

Sustaining the energy and focus involved in doing a good job I think starts to gets tougher the longer you do it.

We know that the nation that goes all-in on innovation today will own the global economy tomorrow. This is an edge America cannot surrender.

America can't provide health care to people who need it. We can't invest in science and technology, which will determine whether or not we are going to be competitive in the long term. There has never been a country on Earth that saw its economy decline and yet maintained its military superiority.

Be the best father you can be to your children. Because nothing is more important.

Politics, differences of religion or race, all that fades away when we are confronted with the awesome power of nature, and we're reminded that all we have is each other.

The countries who out-educate us today will out-compete us tomorrow.
