Joe Biden dealt devastating blow as nearly NINE-IN-TEN voters say he's TOO OLD

The figure also includes 59 per cent who think both Biden and his Republican rival Donald Trump are too old.

Sixty-two per cent of Americans think Trump, 77, is too old to serve a non-consecutive second term in the White House.

However, there is certainly a partisan split between Democrat and Republican supporters.

Almost three-in-four Democrats think Biden is too old but only 35 per cent of Republicans think Trump is too old.

The figure soars among both with independent voters, reaching 91 per cent with Biden and 71 per cent saying the same with Trump.

Biden’s age and competency have been brought into question yet again following the release of Robert Hur’s report into the 46th President’s handling of classified documents.

The 81-year-old, who dodged criminal charges, did face pressure about his age as it accused the former Vice President of being forgetful.

The report said: “It would be difficult to convince a jury that they should convict him – by then a former president well into his eighties – of a serious felony that requires a mental state of willfulness.”

Hur suggested a jury would see Biden as a “well-meaning, elderly man with a poor memory”.

Responding to questions about his age, Biden said: “I am well-meaning. And I’m an elderly man. And I know what the hell I’m doing.

“I’ve been president – I put this country back on its feet. I don’t need his recommendation.”

Biden also fired back after Hur did not remember when his son Beau died.

Biden added: “How in the hell dare he raise that? Frankly, when I was asked the question, I thought to myself, it was none of their damn business.”

However, the 46th President went on to make yet another blunder by describing the Egyptian President Abdel Fattah el-Sisi as Mexico’s leader.

Despite the blunder, Biden's special counsel Richard Sauber wrote: “We request that you revisit your descriptions of President Biden's memory and revise them so that they are stated in a manner that is within the bounds of your expertise and remit.”

He added: “We do not believe that the report's treatment of President Biden's memory is accurate or appropriate.

“The report uses highly prejudicial language to describe a commonplace occurrence among witnesses: a lack of recall of years-old events.”

The issue of classified documents has also engulfed Trump.

Trump, who faces criminal prosecution for deliberately retaining classified material, said in a statement: “THIS HAS NOW PROVEN TO BE A TWO-TIERED SYSTEM OF JUSTICE AND UNCONSTITUTIONAL SELECTIVE PROSECUTION!

“The Biden Documents Case is 100 times different and more severe than mine.

“I did nothing wrong, and I cooperated far more. What Biden did is outrageously criminal.”

Nikki Haley, who is Trump's only remaining Republican rival in the ongoing Grand Old Party primary, also said: “The double standard is glaring.

“Both Joe Biden and Donald Trump were reckless with classified documents.

“If Biden’s defense is old age and forgetfulness, Trump can easily make the same claim. Trump should quickly hire Biden's lawyers.”

But Hur highlighted the key differences between the incidents facing Biden and Trump.

He claimed Trump refused to return classified documents for months and directed other people “to destroy evidence and then to lie about it”.

Whereas, he revealed Biden “turned in classified documents to the National Archives and the Department of Justice, consented to the search of multiple locations including his homes, sat for a voluntary interview, and in other ways cooperated with the investigation”.
