I believe that it is imperative that we learn from the mistakes.

In nearly every religion I am aware of, there is a variation of the golden rule. And even for the non-religious, it is a tenet of people who believe in humanistic principles.

In the 1980s, I was working to reform the schools in Arkansas. Donald Trump was borrowing $14 million from his father to start his businesses. In the 1990s, I went to Beijing and I said women's rights are human rights. He insulted a former Miss Universe, Alicia Machado, called her an eating machine.

I take running for president and being president really seriously. It's a - maybe the toughest job in the world, right? And I knew that there was unfinished business from the successful two terms of President Obama, whom I had served, but that we needed to go further on the economy, on health care, and so much else.

I don't want to rip families apart. I don't want to be sending parents away from children.

I want to try to counter what Donald Trump says because a lot of it is mean-spirited and would hurt people.

I drink tons of water. Just as much water as I can possibly drink.
