A family-friendly "eco-populism" can mobilize and unite millions who, at this point, would be turned off by a more extreme set of demands. The momentum will build, through these early efforts, for more comprehensive solutions.

Sometimes we overemphasize the political system. There are other ways to make a difference. There's technology, there's media, there's business.

[Donald Trump] has a tremendous opportunity, you know, this week, to come out and say I don't want that.

In the U.S., African- Americans, no matter what we do - when we sit in, when we freedom ride, when we kneel in, whatever it is, the initial response from the public tends to be overwhelmingly negative, because basically we're kind of raining on folks' parades. As time goes on, the Muhammad Ali's and all the people that raised those issues, they then become heroes later when people reflect on the courage they showed and the issues that they raised. And Donald Trump is in danger of being a more and more reviled figure as the years go on.

It is the Muslim community that has the best chance of stopping and checking and pushing back on people who are trying to politicize their own faith. So this attack on Islam is an attack on a great faith. It undermines the people who are trying to rescue this faith from these horrible people. It endangers every human being on earth because it accelerates the radicalization of some and emboldens the worst elements of that faith. So this fight is a fight I think that we have to take on.

On the eve of historic fights for health care and clean energy, opponents of reform have mounted a vicious smear campaign against me. They are using lies and distortions to distract and divide. I have been inundated with calls - from across the political spectrum -- urging me to 'stay and fight.' But I came here to fight for others, not for myself. I cannot in good conscience ask my colleagues to expend precious time and energy defending or explaining my past. We need all hands on deck, fighting for the future.
