Sen. Elizabeth Warren of Massachusetts and Sen. Bernie Sanders of Vermont will be part of the Democratic party’s leadership next year.

Senate Democrats unanimously elected Sen. Chuck Schumer of New York Wednesday to replace retiring minority leader Sen. Harry Reid of Nevada next year.

Warren will serve as vice chair and Sanders will be the chair of outreach when Congress convenes in January.
