Michelle Obama: I'll "Think About" Supporting Hillary

This morning on Good Morning America:

ROBERTS: So what if Senator Clinton defeats her husband, becoming the first woman nominee. Could you see yourself working to support the first woman nomination?

OBAMA: I'd have to think about that. I'd have to think about that, her policies, her approach, her tone.

ROBERTS: That's not a given?

OBAMA: You know, everyone in this party is going to work hard for whoever the nominee is. I think that we're all working for the same thing. and, you know, I think our goal is to make sure that the person in the White House is going to take this country in a different direction. I happen to believe that Barack is the only person who can really do that.
