The state chapter of the labor union AFL-CIO has endorsed Democrat Elizabeth Colbert Busch in her bid for the 1st Congressional District.
"Elizabeth's business experience with the maritime industry and Clemson University helps her understand that when labor and management work together everyone wins," union vice-president Erin McKee said in a statement. "Her struggles in life have given her compassion and an understanding of working people's struggles."
Colbert Busch, a Clemson University employee, is one of two Democrats in the race along with 16 Republicans.
The primary is scheduled for March 19.
