ormer Biden press secretary Karine Jean-Pierre announced Tuesday that she’s written a book about a “broken” Biden White House and what she sees as the betrayal of the former president by the Democratic Party.

• Many of her former colleagues think Jean-Pierre — the face of the White House for more than two years — was part of the problem, according to interviews with more than two dozen former Biden administration officials.

Driving the news: Jean-Pierre’s announcement Wednesday led former Biden aides to tee off on her. Many quietly had fumed for years, believing she was incompetent at her job at the White House podium and more interested in promoting herself than Joe Biden.

• News of her book — “Independent: A Look Inside a Broken White House, Outside the Party Lines” — and that she was leaving the Democratic Party was the final straw for many people who’d worked with her.

The fighting within Bidenworld is part of larger post-election angst and grievances amid new reporting of how Biden’s staff tried to hide his physical and mental decline during his presidency.

• Jean-Pierre was a key part of the effort to conceal Biden’s decline, vouching for his fitness and insisting the president, then 81, was “as sharp as ever” even after last June’s disastrous debate against Donald Trump.
