I think the immediate thing is we stand up to protect those people who are in trouble.

The light bulb going off in my head was a fear that in this pivotal moment in history, when America faces so many serious problems, when the middle class and working class of this country are being decimated, that there were not voices out there representing the tens of millions of people who needed a voice. And the idea of going through a campaign where there is not a serious discussion about the most important issues facing America, where there are not voices out there representing people who are hurting - that seemed to me unacceptable.

I will do my best to transform our trade policy and take on these corporations who want to invest in low-income countries around the world rather than in the United States of America.

The reality is we that have a corrupt campaign finance system which separates the American people's needs and desires from what Congress is doing. So to my mind, what we have got to do is wage a political revolution where millions of people have given up on the political process, stand up and fight back, demand the government that represents us and not just a handful of campaign contribution - contributors.

Corporations can't have it both ways. They can't tell Americans how much they want us to buy their products, but then run abroad to avoid taxes or hire cheap labor. American corporations should pay their fair share of taxes and create decent-paying jobs here - not in China.

Donald Trump believes that climate change is a hoax. Now, this is not just a stupid expression, but it is incredibly dangerous.

I believe strongly that we can protect our people without undermining our constitutional rights and I worry very, very much about the huge attacks on privacy that we have seen in recent years - both from the government and the private sector. I worry that we are moving toward an Orwellian society, and this is something I will oppose as vigorously as I can.
