Joe Biden’s longtime White House press secretary Karine Jean-Pierre announced Wednesday she has left the Democratic Party and is writing a tell-all book about the “broken” administration she served.

Jean-Pierre, 50, worked as Biden’s top spokeswoman for two years and eight months and stunned fellow White House alums by announcing her book “Independent: A Look Inside a Broken White House, Outside the Party Lines,” due out on Oct. 21.

“Jean-Pierre didn’t come to her decision to be an Independent lightly,” Hachette Book Group said in a promotional release, which hints that the former Biden spokesperson may focus her ire on figures aside from the 46th president in her account.
