There is no question in my mind that if we summon our resources, both our leadership resources and all of the tools at our disposal, not just military force, which should be used as a last resort, but our diplomacy, our development aid, law enforcement, sharing of intelligence in a much more open and cooperative way. We can bring people together, but it cannot be an American fight.

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.

You have to be a little bit crazy to run for president.

I am somewhat influenced by the years that I've spent trying to actually get things done, whether it was reforming education in Arkansas or a survey and Legal Services Corporation board when President [Jimmy ]Carter appointed me and trying to get lawyers for poor people. I have worked in these areas. I know it's more than just a hope. You've got to translate it into a policy that leads to action.

I believe we should have a full-court press diplomatic effort. If Trump doesn't want to listen to the experts inside his own government, then go to people outside in think tanks and academia who know about this very complicated region, and particularly North Korea.

[Donald Trump] suggestions are not only offensive but, in certain cases, dangerous and sometimes even illegal, like his dismissal of the laws of the United States international law when it comes to torture.

We are stronger together. We are stronger together in facing our internal challenges and our external ones.
