Tina Flournoy, chief of staff to Vice President Harris, is preparing to depart the White House, capping a long list of aides who have left Harris’s office in recent months, and is set to be replaced by Lorraine Voles, a veteran Democratic operative and communications expert. Flournoy has led the vice president’s operation since the start of the Biden administration, overseeing all staff and setting the strategic direction for a historic and high-profile vice president. Before joining the White House, Flournoy had a lengthy career in Democratic politics. She served as President Bill Clinton’s chief of staff and held top roles at the Democratic National Committee and on Al Gore’s 2000 presidential campaign.
