Jean-Pierre, who served as former President Joe Biden ’s top spokeswoman for nearly three years, revealed the move alongside news of her book, Independent: A Look Inside a Broken White House, Outside the Party Lines, set to be released on Oct. 21.

The book’s publisher Hachette, calls it a “groundbreaking, revelatory assessment of America’s broken two-party system” and states that the former flack will take readers “through the three weeks that led to Biden’s abandoning his bid for a second term and the betrayal by the Democratic Party that led to his decision.”
