Former aides who worked directly with then-Vice President Joe Biden in the Obama administration have called current fears over his age “a very real issue” — with some alarmed at how he has become more “frail” and “mumbly.”
“If you watch Joe Biden speak, oftentimes he sounds frail and he sounds more frail than he used to, even in 2019 and 2020,” Jon Favreau, the chief speechwriter for Obama when Biden was vice president, said in a recent episode of the “Pod Save America” podcast.
“The voice sounds frail, and he shuffles more because of the arthritis in his back,” Favreau said, adding that the oldest-ever president also appears “mumbly.”
