The Fight for 15 took center stage at Thursday night’s Democratic debate in Brooklyn, New York. In their most contentious debate of the campaign, Hillary Clinton and Bernie Sanders faced off over Wall Street, saving Social Security, Israel, guns and more. CNN moderator Wolf Blitzer asked Clinton if, given her support for a $12-an-hour minimum wage, she would sign a bill raising it to $15 an hour.

Wolf Blitzer: “If a Democratic Congress put a $15 minimum wage bill on your desk, would you sign it?”

Hillary Clinton: “Oh, of course I would. And I have supported—I have supported the Fight for 15. I am proud to have the endorsement of most of the unions that have led the Fight for 15.”

Sen. Bernie Sanders: “I am sure a lot of people are very surprised to learn that you supported raising the minimum wage to 15 bucks an hour.”
