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.

Donald Trump doesn't release his tax returns and is indebted to foreign banks and foreign lenders.

The cavalier casual way that Donald Trump talks about nuclear weapons is not only frightening but it goes counter to more than 70 years of bipartisan, presidential leadership of Republicans and Democrats who believed that we have to prevent other countries from getting nuclear weapons and we have to do what we can to decrease the number of nuclear weapons in the world.

I don't believe that people vote for President based on spouses. I don't even think they vote much based on vice presidents or any other factor. I think they choose between the two people who are running.
