Tarryl ClarkThe Minnesota Nurses Association is the latest union to endorse Tarryl Clark in her bid to unseat U.S. Rep. Michele Bachmann. The Democratic challenger has picked up support from practically every sector of organized labor in recent weeks.

“Tarryl has been a long time champion of nursing and working families,” said Linda Slattengren, president of the Minnesota Nurses Association, in a statement announcing the endorsement. “She has been an advocate for universal health care both in the legislature and in the community. We look forward to working with her in Congress.”

Clark is seeking the DFL nomination. Her only announced opponent is Maureen Reed.
