The hosts of "Pod Save America" and Jon Stewart are questioning former President Joe Bidens mental acuity following the release of Jake Tapper andAlex Thompsons book, "Original Sin.""So everybody goes on television and goes, You dont understand," Jon Stewart said during a Thursday episode of his podcast, "The Weekly Show with Jon Stewart," discussing how people would try to frame concerns about Bidens health. "I sit with this guy. Hes the smartest one in the room. I cant keep up with him. Im exhausted. I went to a meeting, and he was using words I didnt even know were words! They were fantastic! I had to look them up. Hes the smartest man in the world.'"On Tuesday, "Original Sin," which looks in part at the efforts made by top Biden aides and allies to hide the truth about Bidens mental and physical health, providing a depiction of a president who was routinely confused and disorientated during his term, was released.BIDEN INSIDER WAS REPORTEDLY 'AMAZED' AT THE MEDIA COVERAGE THEY WERE ABLE TO SPINDuring his podcast Thursday, Stewart talked about how he thinks those in Bidens circle tried to control what the public saw."You know, Kamala Harris comes out, I sit with this man. You dont understand," Stewart said. "You dont see it. And Im like, Oh, has anyone filmed that? Because you should show that. Because it was a very simple case to puncture. People are saying, Im a little concerned about his stamina and cognitive ability. Heres how we can dispel that. Just put him out there and let him show us how f---ing smart and they wouldnt do it. Because they knew they couldnt."Jon Favreau, former President Barack Obamas head speechwriter from 2005-2013, said that the people closest to Biden were not honest about his decline."Throughout Bidens term, you had it with the age issue, you also had it with inflation, right," Favreau said."In the Biden administration, a lot of elected Democrats were like, Oh, look at all the statistics and the numbers," he added. "And then poll after poll and focus group after focus group would have people be like, No, prices are high and its really bothering me. And wed just be like, Thats just the media. Or Thats just Republicans. And I think the same thing happened around Joe Bidens age. The closer you got to Joe Biden, the closer the adviser or the family member, the more I think they were not just lying to the American people, but lying to themselves."Favreau also said that he thinks Democrats struggle with accepting and telling the truth."I think a big problem with the Democratic Party over the last several years, decade maybe, maybe even back to the Iraq war, we have a hard time hearing hard truths and admitting hard truths to ourselves,"Favreau said. "And then we have a hard time telling hard truths to the voters."Favreau is featured in "Original Sin" in an anecdote where he and his "Pod Save America" co-hosts Dan Pfeiffer and Jon Lovett met with Biden at the White House on April 26, 2024. The book described them as "deeply disturbed" after their discussions with Biden that night, with the authors describing the president as rambling and "incoherent."FLASHBACK: WHITE HOUSE PRESS SEC KARINE JEAN-PIERRE LAUGHS OFF QUESTION ON BIDEN'S HEALTH IN 2022However, in aFeb. 13, 2024 episode of "Pod Save America," Favreau seemed to downplay concerns about Bidens health."The number one concern that people have had about Joe Biden is his age. Those concerns have predated Robert Hur, they have predated anything Trump has said it is not just about people who see like out of context clips or that the Republicans put out, or crazy TikToks or whatever else," he said.This discussion with his "Pod Save America" hosts came days after Special Counsel Robert Hurs report was released onFeb 5, 2024, looking at the former presidents handling of classified documents."If you watch Joe Biden speak, often times he sounds frail, and he sounds more frail than he used to even in 2019 and 2020," Favreau said. "Now that may, and I think it doesn't have anything to do with how sharp he is mentally, but the voice sounds frail and he shuffles more because of the arthritis in his back so for most people in the country who are just watching him be president what do they see when they turn on the television? They see him shuffle and they hear him and he is swallowing a lot more of his words now obviously he's had a stutter but it doesn't sound like the stutter did even in 2020 he's just soft-spoken and quiet."Co-host Tommy Vietor, who worked for Obama for almost a decade, appeared to agree withFavreaus dismissiveness."All the commentary about the age and Biden's memory which seemed unfair or ad hominem at worst, and then second there is a debate about Biden's age and fitness for office that was already happening. This just kicked it up and focused the media's attention on it in a very damaging way via this DOJ report," Vietor said during theFebruary 2024 episode.On Sunday, Bidens prostate cancer diagnosiswas announced, with his spokesperson telling Fox News days later that the last time he received a blood test that screens for prostate cancer wasin 2014.
