NEW YORK — Former White House press secretary Karine Jean-Pierre is releasing a book this fall that offers an in-depth examination of President Biden’s choice not to seek reelection and advocates for considering alternatives to the current two-party system.

Jean-Pierre has changed her affiliation to independent after having served in two Democratic administrations, as reported by Legacy Lit, an imprint of the Hachette Book Group, which will publish “Independent: A Look Inside a Broken White House, Outside the Party Lines” on October 21.

“Until January 20, I was responsible for speaking on behalf of the President of the United States,” Jean-Pierre, the first Black woman and openly gay person to serve as White House press secretary, stated in a release on Wednesday.

“At noon on that day, I became a private citizen who, like all Americans and many of our allies around the world, had to contend with what was to come next for our country. I determined that the danger we face as a country requires freeing ourselves of boxes. We need to be willing to exercise the ability to think creatively and plan strategically.”

Jean-Pierre, 50, succeeded Jen Psaki as press secretary in 2022 after previously serving as deputy press secretary and also working as a senior adviser during Biden’s victorious 2020 campaign. During President Barack Obama’s first term, she was a regional political director.

Jean-Pierre was criticized at times for being evasive about Biden’s physical condition. Wednesday’s announcement from Legacy Lit says that she 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.”

“She presents clear arguments and provocative evidence as an insider about the importance of dismantling the torrent of disinformation and misinformation that has been rampant in recent elections and provides passionate insight for moving forward,” the announcement said.

Jean-Pierre’s book could be one of the few by former White House press secretaries to make news. Scott McLellan, President George W. Bush’s press secretary from 2003-2006, made headlines when he criticized Bush and other administration officials in the 2008 bestseller “What Happened.”
