Jake Tapper's book is 'a slap in the face' to anyone who questioned Biden's fitness for office, Lindy Li says

Tapper was roasted online earlier this year when his upcoming book, "Original Sin: President Biden's Decline, Its Cover-Up, and His Disastrous Choice to Run Again," was announced. The book, co-written by Axios journalist Alex Thompson, was attacked as hypocritical after critics unearthed a 2020 video of Tapper lecturing then-Trump 2020 campaign advisor Lara Trump for calling out Biden's mental faculties.

"Sort of reminds me... Jake Tapper announced he has a book about the scandal around Biden's health. It's like, 'Dude, you were running cover for it for three years while some of us were talking about it literally four or five years ago,'" host Dave Rubin said. 

Li rolled her eyes as Rubin mentioned Tapper's book, saying he "pisses me off so much."

Li said she knew Biden "in a private capacity," and didn't see the CNN anchor around enough for him to have insight into his fitness for office behind-the-scenes.  

"With Jake Tapper, he wasn't in the room, and I've never seen him at any events, so all the intel from this book is second-hand," Li said. 

"Let's be honest what it was," she continued. "It was an out-right lie that he was cognitively fit." 

Li said Tapper's book "is like a slap in the face to those of us who were punished for bringing it up."

Li also claimed her appearances on CNN dried up once she publicly said Biden was too old to seek another term.  

"I used to be on it all the time. I was a regular," she said, referring to CNN, not Tapper's program specifically. 

When asked for comment, CNN directed Fox News Digital to a representative for Tapper who is handling the book. 

"Jake and Alex's book contains first-hand accounts of President Biden's state based on interviews with more than 200 people," the representative continued. "Stay tuned for what they discovered."

Li previously said her decision to leave the party "wasn't easy" but was the "result of a decade-long progression."

"It took a while for me to get here over the course of the past year. I just realized that the values of the Democratic Party are so incongruous to mine," Li said. "It just contradicts everything I believe, everything from open borders to woke and DEI insanity. It's just not my party anymore."
