You probably know the name of Rosa Parks. You probably know that her refusal to move to the colored section in the back of a city bus sparked the Montgomery bus boycotts, one of the pivotal moments in the American civil rights movement.

I think it's fair to say that Nina Simone was a prodigy.

Right now, I don't believe [Donald Trump]. I don't trust him.

I noted, though, that other strong critics of Donald Trump did attend the inauguration. Hillary Clinton went. Vermont Senator Bernie Sanders went. I saw Massachusetts Senator Elizabeth Warren. I saw Congressman James Clyburn, all of whom have been critics of Donald Trump.

Donald Trump, the Republican frontrunner, bypassed the debate before the Iowa caucuses because he objected to the participation of moderator Megyn Kelly as well a press release defending her.Beyond the Trump tantrum, we wondered if this had something bigger to say about the state of the media and politics and how politics is practiced today.

Otherwise, their only engagement I'm going to have with [Donald Trump] is fighting back against their attempts to undo Dodd-Frank, their attempts to destroy the Consumer Financial Protection Bureau and all of those things.

If [Donald Trump] comes forward and if he does that, then, of course, there will be some engagement.
