After a close victory over Minnesota Congressman Keith Ellison, Perez appointed Ellison as Deputy Chair in an attempt to lessen the divide in the Democratic Party after the contentious 2016 Democratic presidential primaries, which saw conflicts between supporters of Hillary Clinton and Bernie Sanders. Perez was seen as being more in line with the Clinton wing, while Ellison was more in line with the Sanders wing. The role's revival in 2017 has been described by critics as largely titular and ceremonial.
