Firebrand Sen. Elizabeth Warren joined Senate Democratic leadership Thursday after Senate Democrats convened Thursday to assemble a leadership team for their role as the incoming minority caucus . Senate Majority Leader Harry Reid , who was elected to continue leading the Democratic caucus in the minority , said he tapped Warren to join Thursday because of who she is . `` I expect her to be Elizabeth Warren , '' Reid said explaining what he expects the Massachusetts senator to do as part of the leadership team . Warren , known for hitting populist notes in stump speeches , said she was excited to join the Democratic leadership to continue fighting for the middle class . `` Wall Street is doing very well , CEOs are bringing in millions more and families all across this country are struggling , '' she said . `` We have to make this government work for the American people . '' And flanked by Warren and the two other women who are joining his leadership team ( Sens . Amy Klobuchar and Debbie Stabenow ) , Reid said women in the Senate have brought positive change to the legislative body . `` I 've seen this institution change for a lot of reasons , '' Reid , who has been in Congress for three decades , said . `` One reason it has changed for good is because of women . Women think differently than men . '' Reid also insisted that Democrats would stray from replicating what he described as an obstructionist Republican minority once his party loses the gavel . `` This is not get-even time , '' Reid said . `` I do not intend to run the Democratic caucus like the Republican caucus has been run in the minority . '' A Senate Democratic leadership aide said earlier that Reid would like Warren to join the leadership because he `` trusts her and her judgment . '' And while not every Senate Democrat wants Warren , a high-profile , liberal junior senator in a leadership post , the leadership aide said `` Reid will get his way . '' Sen. Jon Tester of Montana also joined the leadership team and will head the Democratic Senatorial Campaign Committee as Democrats look to reclaim the majority in 2016 . One Democratic senator , Chris Murphy of Connecticut , said the inclusion of Warren is a sign the party mistakenly moved away from core Democratic stances -- such as defending Obamacare on the campaign trail -- and needs to be more focused on middle class issues like raising the minimum wage . `` There 's nobody better than Elizabeth at talking to people who feel this sense of very real economic disenchantment , '' Murphy said . Despite the mid-term election losses , Reid and the other top members of the Democratic leadership were all re-elected , although two centrist members of the caucus voted against Reid . `` When you have an election like this , common sense says we need to change things , '' said Sen. Claire McCaskill , D-Missouri . `` The voice was very loud and unmistakable that most Americans , and most Missourians , want us to change things . To me that means changing leadership and it was just that simple . '' Sen. Joe Manchin said the Democrats ' problems are deep rooted and change is needed . `` I voted for a change and that change was not voting for this leadership , '' Manchin told reporters . The top GOP leaders were all re-elected : Sen. Mitch McConnell of Kentucky will become majority leader , flanked by Sen. John Cornyn of Texas , Sen. John Thune of South Dakota , Sen. John Barrasso of Wyoming and Sen. Roy Blunt of Missouri . Sen. Roger Wicker of Mississippi beat out Sen. Dean Heller of Nevada to lead the National Republican Senatorial Committee . Elizabeth Warren : I 've been treated differently .
