We know that Donald Trump has shown a very troubling willingness to back up Putin, to support Putin, whether it's saying that NATO wouldn't come to the rescue of allies if they were invaded, talking about removing sanctions from Russian officials after they were imposed by the United States and Europe together, because of Russia's aggressiveness in Crimea and Ukraine, his praise for Putin which is I think quite remarkable.

I think that we have to be constantly asking ourselves, 'How do we calculate the risk?' And sometimes we don't calculate it correctly; we either overstate it or understate it.

For 30 years, I've produced results for people.

When I was a Senator from New York, I represented and worked with so many talented principled people who made their living in finance. But even thought I represented them and did all I could to make sure they continued to prosper, I called for closing the carried interest loophole and addressing skyrocketing CEO pay. I also was calling in '06, '07 for doing something about the mortgage crisis, because I saw every day from Wall Street literally to main streets across New York how a well-functioning financial system is essential.

People like Donald Trump, who paid zero in taxes, zero for our vets, zero for our military, zero for health and education, that is wrong.

I really deplore the tone of his campaign and the inflammatory rhetoric that he is using to divide people. I don`t know that Donald Trump has any boundaries at all.

I mean, I'm a big believer in talking to people when you can and trying to solve problems when you can.
