You've got to ask yourself, why won't Donald Trump release his tax returns? I think there may be a couple of reasons. First, maybe he's not as rich as he says he is. Second, maybe he's not as charitable as he claims to be. Third, we don't know all of his business dealings, but we have been told through investigative reporting that he owes about $650 million to Wall Street and foreign banks. Or maybe he doesn't want the American people to know that he's paid nothing in federal taxes.

Many of the fights that are going on are not ones that the United States has either started or have a role in. The Shia-- Sunni split, the dictatorships that have suppressed people's aspirations, the increasing globalization without any real safety valve for people to have a better life. We saw that in Egypt. We saw a dictator overthrown, we saw Muslim Brotherhood president installed and then we saw him ousted and the army back.

Whether I am meant to or not, I challenge assumptions about women. I do make some people uncomfortable, which I'm well aware of, but that's just part of coming to grips with what I believe is still one of the most important pieces of unfinished business in human history - empowering women to be able to stand up for themselves.

We know that we have to have the right combinations of government policies and private sector energy and dynamism. Getting that balance right is what I know President Obama has tried to do, and at every turn he's been stopped.
