Rep. Jim Clyburn (D-SC) endorsed Rep. Haley Stevens (D-MI) in Michigan’s Democratic Senate primary, adding another influential voice to her growing list of supporters from the Congressional Black Caucus.

“I’ve been proud to have Haley by my side through some of the toughest fights against Donald Trump and fighting to lower costs for working families,” Clyburn said in a statement to Michigan Chronicle. “From taking on Big Pharma to cap the cost of prescription drugs to bringing back good-paying union manufacturing jobs to Michigan to her work as Chief of Staff on President Barack Obama’s auto rescue, helping save 200,000 Michigan auto jobs, Haley is a fighter for Michigan, and she delivers for Michigan. I’m honored to endorse her campaign for U.S. Senate.”
