Jen O’Malley Dillon, who served as the campaign manager for President-elect Joe Biden this year, will serve as the Deputy Chief of Staff in the upcoming Biden - Harris White House.

President-elect Joe Biden said on Tuesday: “I am proud to announce additional members of my senior team who will help us build back better than before.

Responding to the announcement, O’Malley Dillon said in a tweet that working for Joe Biden is “absolutely the honor of my life.”

Having served as the campaign manager for President-elect Joe Biden, a role she was hired for in March when Biden was still seeking the Democratic presidential nomination, O'Malley Dillon has become the first woman to successfully manage a Democratic presidential campaign.
