The United Automobile Workers plans to endorse Rep. Keith Ellison in the race for chair of the Democratic National Committee, according to two sources with knowledge of the union’s plans.

The UAW is one of the remaining major labor groups that hasn't weighed in on the race for DNC chair. Ellison has already picked up support from other major labor organizations including the AFL-CIO, AFSCME President Lee Saunders, and the International Brotherhood of Electrical Workers.


It's unclear when the endorsement will happen. When asked about the endorsement, UAW senior communications adviser Brian Rothenberg said, “When we’re ready to put out the release we will.”

Meanwhile, the Service Employees International Union will not issue a formal endorsement, but will urge SEIU DNC members and others to vote for Ellison, according to a source familiar with the matter.

But not all major labor organizations are siding with Ellison in the race for DNC chair. Former Labor Secretary Tom Perez, Ellison's highest-profile competitor, has also been endorsed by the United Farm Workers, the International Association of Fire Fighters, and the United Commercial Workers International Union.
