Leading political figures fear there may be a very sinister reason for Biden's disappearance since dropping out of 2024 race | 22 July 2024 | Political figures on both left and right have suggested U.S. President [sic] Joe Biden is seriously-ill - or even dead - over the way he announced his departure from the 2024 election race. Controversial congresswoman Lauren Boebert, 37, posted on X on Monday asking for "proof of life" from the 81-year-old and even gave the president a deadline. The Republican firebrand said: "I demand proof of life from Joe Biden today by 5:00pm. He needs to get in front of some camera and discuss if he's aware that he dropped out. Hiding is completely unacceptable." Biden was last seen on July 17 and is currently receiving treatment for a mild Covid infection at the White House, with his team sharing their latest update Monday.
