In the last presidential election Obama and Romney raised about $1 billion each. The Koch brothers, the second wealthiest family in America, now say they will raise nearly $1 billion for the 2016 elections. When one family can raise as much as an entire party, the system is broken. This is oligarchy, not democracy. We must overturn Citizens United.

There is a reason why these people [from Wall Street] are putting huge amounts of money into our political system. And in my view, it is undermining American democracy and it is allowing Congress to represent wealthy campaign contributors and not the working families of this country.

At a time of massive inequality, I think we can raise substantial sums of revenue to address the needs of working families, the elderly, and the children, by asking those people who are doing phenomenally well to start paying their fair share.

Israel's right to exist in peace and security is not in debate.

Secretary [Hillary ] Clinton is absolutely right, there are people, Koch brothers among others, who have a group called Concerned Veterans of America, funded by the Koch brothers. The Koch brothers, by the way, want to destroy Social Security, Medicare, Medicaid, every governmental program passed since the 1930s. Yes, there are people out there who want to privatize it.

We must never allow demagogues to divide us up by race, by religion, by national origin, by gender, or sexual orientation. Black and whites, Latino, Asian-American, Native American, Christian, Jew, Muslim, and every religion - straight or gay, male or female - we must stand together. This country belongs to all of us.

What we need to do is lead an international coalition which includes very significantly the Muslim nations in that region who are going to have to fight and defend their way of life.
