Naomi Biden offered a "first-hand" rebuke of the upcoming book on the former president's reported health decline.

Naomi Biden slammed Jake Tapper's new book about her grandfather, former President Joe Biden, calling it "political fairy smut" in a social media post.The CNN anchor's book has ignited fierce criticism from liberals and media observers who accuse Tapper of profiting from a narrative he once helped downplay: Biden's perceived mental and physical decline during his final year in office.

Tapper‘s book, “Original Sin: President Biden’s Decline, Its Cover-Up, and His Disastrous Choice to Run Again,” co-authored with Axios reporter Alex Thompson, will be available to purchase on May 20. Just one day ahead of its release, former President Joe Biden’s granddaughter tore into what she called a “silly book.”
