Leading political figures fear there may be a very sinister reason for Biden's disappearance since dropping out of 2024 race

Political figures on both left and right have wildly suggested US President Joe Biden is seriously ill because of the way he announced his departure from the 2024 election race.  

Controversial congresswoman Lauren Boebert, 37, posted on X on Monday demanding 'proof of life' from the 81-year-old and even giving the president a deadline. 

The Republican firebrand - who has previously been embroiled in multiple scandals relating to conspiracy theories - 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 recovering from a mild Covid infection. On Sunday, he announced on X that he would no longer be seeking re-election.

There's no suggestion or known evidence that Biden is suffering another, more serious health issues. Any such illness could present a major national security issue and would raise questions about whether he needs to step down as president ahead of the November election. 

Journalist Glenn Greenwald - an anti-Biden left-winger - also posted on social media deeming it 'strange and wrong' that Biden hadn't given a televised announcement or appeared in person since revealing his bombshell decision.

President Biden announced in a letter published to his social media that he was stepping down from his bid to be reelected 

Greenwald wrote: 'I don't endorse Biden conspiracies, but still: It's strange and wrong that Biden hasn't spoken given the historic magnitude of his announcement. 

'Having a President drop out by tweet and then disappear is bizarre. If he's well enough to decide, then he's well enough to speak.'

Alongside Boebert, fellow GOP representative Marjorie Taylor Greene described Biden's decision to drop out in similar conspiratorial terms. 

Without any evidence, Greene posted on X saying: 'There’s a soft civil war happening in the deep state and the elites in power.

'The Democrats, the IC, and their activists in the media have been lying to us saying there’s nothing wrong with Biden for years. 

'Next, they start a coup against him demanding he drop out of the race when they couldn’t hide it anymore.'

Greene is notorious for backing multiple outlandish conspiracy theories, including the QAnon claim that Trump is locked in a battle against Satan-worshipping Democrats and celebrities. 

Biden's health appears to be what ultimately ended his campaign, after a disastrous TV debate against Donald Trump, 78, last month.  

Worries about Biden's wellbeing were exacerbated Sunday after his younger brother claimed illness had been a factor in his decision to stand down. 

Frank Biden told CBS: 'I'm incredibly proud of my brother. Selfishly, I will have him back to enjoy whatever time we have left.'

But a Biden family source poured very hot water on Frank's claims. 'Frank Biden suffers from alcoholism and hasn't spoken to his brother in weeks,' the source said. 'What he said ... is completely untrue.'

A top Parkinson's disease specialist visited the White House multiple times this year, although officials have insisted Biden is in good health.  

Biden made the announcement that he was backing out of the presidential race by sharing a letter to his social media on Sunday afternoon. 

The president has been isolating with Covid-19 at his holiday home in Rehoboth Beach, Delaware, where his team composed the letter. 

On Monday, his physician issued a letter saying that Biden was almost resolved completely of his symptoms. 

Dr. Kevin O'Connor wrote in his letter that his pulse, blood pressure, respiratory rate and temperature remained normal. 

On Saturday evening, Biden summoned to his side two men who have been there since his political start, advisers Steve Ricchetti and Mike Donilon. 

It was Ricchetti and Donilon who brought with them devastating new data which would help to make up Biden's mind.

They revealed the latest internal campaign polling, taken since the debate, which showed he could no longer beat Trump. 

After his announcement, Kamala Harris announced she was running for the Democratic presidential nomination.
