Susan Rice: “Vladimir Putin is doing the happy dance.”

You know, we have in Donald Trump a leader who is not running to be the president of the American people. He's running for his own self-interest to try to stay out of jail.

With Joe Biden, we have strong leadership that has strengthened our alliances not only in Europe, but in Asia and around the world, which makes America more secure.

I take that very seriously, and I think we all should.

America should aim to win the A.I. race, provided that the race can be won safely.
