WASHINGTON (AP) — The United Farm Workers on Tuesday announced its endorsement of President Joe Biden for reelection, saying that the Democrat has proven throughout his life to be an “authentic champion” for workers and their families, regardless of race or national origin.

The farm workers’ union was co-founded by Cesar Chavez, the late grandfather of Julie Chavez Rodriguez, who Biden named as his 2024 campaign manager. Her father, Arturo Rodriquez, is a past UFW president.

Julie Rodriguez and “special guests” were expected to formally announce the endorsement later Tuesday at Muranaka Farms in the city of Moorpark in southern California.

“Throughout his life, President Biden has been an authentic champion for workers and their families, regardless of their race or national origin,” UFW President Teresa Romero said in a written statement. “The United Farm Workers has seen first hand the positive impact that President Biden has made in the economic standing, labor rights, and daily lives of farmer workers across America.”

The UFW endorsement came as Biden on Tuesday flew to the Detroit area to join a picket line with United Auto Workers members who are on strike against Ford, General Motors and Stellantis.

The farm workers’ union endorsed Biden in 2020 over Republican President Donald Trump, who leads the field of GOP candidates vying for the party’s 2024 presidential nomination and the chance to challenge Biden.

Julie Rodriguez said in a written statement that the UFW’s organizing has always been about fighting injustice and supporting working people, values that she said are at stake in the election.

“Some of my most cherished conversations with President Biden have been about the legacy of my grandfather and the organizing power of the UFW, because Joe Biden is a real fighter for workers, for Latinos, and for every human’s dignity,” said Chavez Rodriguez. She was a top White House adviser to Biden before he named her as campaign manager earlier this year.

The union said it will organize, train and dispatch skilled organizers and Spanish-speaking members to key states, including Arizona, Nevada, Texas, Michigan and Georgia, as it did in 2020.
