President Joe Biden has been endorsed by another trade union, this time for retirees, on the heels of winning the support of the United Auto Workers.

The 81-year-old’s campaign welcomed the endorsement from the Alliance for Retired Americans on Tuesday, with campaign manager Julie Chavez Rodriguez underscoring how its more than 4 million members, associated with the AFL-CIO, will provide critical organizing power for the president’s reelection bid.
