Biden names Julie Chávez Rodríguez as his campaign manager.

As President Biden announced his re-election bid on Tuesday, he named Julie Chávez Rodríguez as his campaign manager, elevating a senior adviser and the highest-ranking Latina in the White House.

Ms. Chávez Rodríguez, a veteran of the Obama administration and of Vice President Kamala Harris’s political orbit, also worked on Mr. Biden’s 2020 presidential campaign before becoming director of the White House Office of Intergovernmental Affairs. She is the granddaughter of Cesar Chávez, the prominent labor leader for farmworkers.

Mr. Biden has a small circle of close aides, many of whom have known him for decades, and breaking into that world can be a challenge. But several Democrats said that Ms. Chávez Rodríguez had impressed top advisers, adding that she was seen as a trustworthy team player with strong political relationships and experience.

She is also closely connected to Ms. Harris. Ms. Chávez Rodríguez, a Californian herself, served as Ms. Harris’s state director when she was a California senator, and on her 2020 presidential campaign.

Quentin Fulks, a Democratic strategist who served as campaign manager for Senator Raphael Warnock of Georgia in his successful re-election bid last year, was named principal deputy campaign manager.

“Julie and Quentin are trusted, effective leaders that know the stakes of this election and will bring their knowledge and energy to managing a campaign that reaches all Americans,” Mr. Biden said in a statement.
