Elizabeth Warren Is Waiting To See Just How Progressive Hillary Clinton Is

Liberal hero Sen. Elizabeth Warren (D-Mass.) said Tuesday that she's waiting to see how progressive a Hillary Clinton presidential campaign would be.

Asked by the Rev. Al Sharpton on MSNBC's "Politics Nation" whether Clinton would be a "progressive warrior," Warren didn't exactly give a ringing endorsement.

"You know, I think that's what we gotta see," Warren said. "I want to hear what she wants to run on and what she says she wants to do. That's what campaigns are supposed to be about."

Warren's comments follow her private meeting with Clinton in December, when Clinton asked Warren for policy recommendations, The New York Times reported.

Warren has repeatedly insisted that she's not interested in a presidential run, and has said publicly that she hopes Clinton will make a White House bid. Her statements haven't stopped some progressive groups from trying to persuade her to change her mind.
