PITTSBURGH — The United Steelworkers union, which represents close to 20,000 rubber workers at 18 U.S. tire plants, is endorsing Joe Biden for president.
The union said the move came after candidates were sent a detailed questionnaire last fall seeking their views on "key issues affecting working people."
President Trump did not provide answers, the union said.
"Vice President Biden has long been a friend of workers and our union," USW International President Thomas Conway said. "The USW is proud to stand with him now."
USW includes 850,000 members in a variety of industries, including rubber, chemicals and automotive supply.
