The United Auto Workers endorsed President Joe Biden for reelection on Wednesday, putting a high-profile union behind the Democrat’s 2024 campaign well ahead of the general election.

Shawn Fain, the union’s president, announced the UAW’s backing during the union’s convention in Washington, D.C. He said in a speech to members that Biden would give workers “the best shot” at organizing, winning strong union contracts and fighting “the billionaire class.”

He also took several swipes at former President Donald Trump, the likely GOP nominee.

“This November we can stand up and elect someone who stands with us… or we can elect someone who will divide us and fight us every step of the way,” Fain said.

The UAW has around 400,000 members and is coming off ahistoric and successful six-week strike against the “Big 3” automakers, Ford, General Motors and Jeep parent company Stellantis. Biden took the highly unusual step as sitting president of visiting apicket line in Michigan to show his support for the strikers.
