Rep. Keith Ellison, D-Minn., formally announced his bid to run the Democratic National Committee on Monday, calling for the Democrats to “rebuild” the party after losing the White House and Congress in the elections last week.

“This election cycle, we did not motivate enough people to the ballot box,” Ellison said in his announcement. “We must champion the challenges of working families and give voters a reason to show up at the polls in 2018 and beyond. We must build a bench not just for federal candidates, but for state and local candidates across the nation.”
