"I take my cue on every part of this from Bernie himself," Warren said on MSNBC's "The Rachel Maddow Show" Thursday night. 
"I also think that what Bernie Sanders did was just powerfully important. He ran a campaign from the heart, and he ran a campaign where he took those issues and he really thrust them into the spotlight," Warren said. "He brought millions of people into the political process, millions into the Democratic Party, and for me, that's what it's all about."
Warren said Sanders is helping to guide the nation in a positive direction.
"Bernie has given us these issues. He's given us this moment. He's brought this light to it that we really can help push this country in the right direction," Warren said. 
Despite her respect for Sanders, Warren gave a strong endorsement to Clinton, calling her a "fighter."
