Discussions about US President Joe Biden’s age and health have taken center stage as he prepares for his re-election campaign in 2024. Biden, who turned 81 in November 2023, is the oldest sitting President in US history. Questions about his physical and cognitive abilities persist, especially given the demanding nature of the presidency. Several recent videos depict Biden looking frail and confused at events.

In one video, he stands unusually still for 30 seconds during a White House Juneteenth concert as others around him dance. In another, he ‘salutes’ Italy’s Prime Minister Giorgia Meloni. Some users claim, without proof, that Biden is being impersonated using CIA mask technology. A widely circulated video on X suggests this impersonation theory by highlighting changes in Biden’s appearance, such as earlobes, chin, and skin texture, and alleging alterations in his signature.

The video, viewed nearly 5 million times, has generated mixed reactions. Some users express belief in the theory, noting differences in Biden’s appearance. Others doubt the doppelganger theory, arguing that it would be impossible to replicate Biden’s mannerisms and personal relationships completely. Another perspective suggests that medical conditions and medications could account for changes in Biden’s appearance and behavior.

This is not the first time such claims have gone viral. A similar claim last year, involving a tweet sharing a CNN clip of Biden’s return to the US after his Israel visit, gained over 2.8 million views but lacked evidence. As Biden’s re-election campaign progresses, discussions about his health and appearance continue to be a focal point.
