Biden, 81, is blasted by CNN for repeating lie that he used to drive an 18-wheeler...after spending one night as passenger in cargo truck in 1973

President Joe Biden repeated a lie he's told in the past about having driven an 18-wheeler truck at a speech in Florida Tuesday. 

At 81, the oldest president in American history, Biden has remained a gaffe machine throughout his presidency, often re-telling lies about his biography that have been repeatedly debunked, even by mainstream outlets.

At Hillsborough Community College in Tampa Bay on Tuesday, Biden claimed to have driven a big rig.

'I used to drive an 18-wheeler,' he said, as he attempted to discuss how he'd negotiated pensions for labor unions.

Biden was called out by CNN along with conservative-leaning media for the lie but it's not the first time the president has made the bizarre claim.

In 2021, Biden was caught off-camera by a local news channel's microphone during a visit to a Mack Truck facility in Pennsylvania, making the claim that he had driven such trucks before.

'I used to drive an 18-wheeler, man,' Biden was heard saying on Wednesday in a video later posted to Twitter. 'I got to.'

Large trucks such as the one Biden gave a speech in-front of during the visit to the facility require a special license to drive, and there is scant evidence that he has ever driven an 18-wheeler truck as he was heard claiming. 

'There is *zero evidence* that Biden 'used to drive an 18 wheeler,"' tweeted the RNC's Zach Parkinson, who is also the director of 'RNC Research' whose twitter account posted the video online.

'The extent of Biden's trucking experience is that he **rode in** a truck once, for one night in 1973 (he made sure to return home by plane though),' he said.

Parkinson cited a 1973 opinion piece written by Biden, then a Democratic senator, in which he recalled taking a 536-mile ride from his home state of Delaware to Ohio in a '47,000 pound cargo truck'.

Biden wrote at the time:  'I made the trip because I wanted a firsthand account from the truckers, who say they carry 50 per cent of all the goods shipped within the United States. They make a case worth listening to.'

In a news story about Biden's journey, it is noted that he made the return journey back to Washington D.C. by plane.

The flub wasn't even Biden's first on Tuesday, as the president suffered another gaffe during a speaking event as he tried to paint his opponent, former President Donald Trump, as untrustworthy.  

He called out Trump, his 2024 general election opponent, as the sole person responsible for the 'cruelty and chaos' that's occurred after the overturn of Roe v. Wade. 

However, when he did so, he accidentally asked: 'How many times does he have to prove we can't be trusted?' 

ABC News tried to cover for the president, replacing the word 'we' with 'he' in describing the speech, though he was clearly heard saying 'we.' 

In 2024 alone, Biden has made several mistakes, publicly forgetting the name of Russian dissident Alexei Navalny's widow, forgetting a German chancellor he'd spoken to died in 2017 and confusing the leaders of Egypt and Mexico. 

Then, there's the matter of the shocking transcript of his testimony to former Special Counsel Robert Hur.

Hur was appointed special counsel by Attorney General Merrick Garland in January 2022 to investigate the president's handling of classified files based on a range of areas including Afghanistan. 

According to the transcript of the two-day interview reviewed by DailyMail.com ahead of Hur's highly-anticipated congressional testimony, Biden brought up Beau's death in the context of a book he wrote published in 2017.

'What month did Beau die?' Biden asked to himself during the hours-long sit down on October 8, 2022.

'Oh God, May 30th,' he seemingly responded. But the president had to be reminded about the year in which his oldest son died because he could not remember.

A White House attorney stepped in to state that the year of Beau's death was 2015.

'Was it 2015 he died?' Biden again questioned out loud. The president then went on to ask if Donald Trump was elected in 2017, to which another White House attorney jumped in to correct him that it was 2016. 

The mix-up of Beau's death date during the interview directly contradicts Biden's fiery denial that it ever occurred. 

Hours after Hur put out his scathing report on February 9, Biden engaged in a furious tirade from the White House saying 'I know what the hell I am doing!' and insisting that 'my memory is fine.'

Similarly, Biden has several times erroneously said in speeches that his eldest son died in Iraq. 

'My son was a major in the US Army. We lost him in Iraq,' Biden told the troops in Iwakuni on Thursday.

Biden, at 81 years old, the oldest president in American history, appeared before supporters at a community college in Tampa, one week before Florida bans abortions past six weeks. 

Beau Biden, who served as Delaware's attorney general and in the Delaware Army National Guard in the Iraq War, died at age 46 in 2015 from brain cancer at the Walter Reed National Military Medical Center in Bethesda, Maryland. 

It was at least the third time America's oldest living president - gearing up for a run for a second term in 2024 - spoke misleadingly about his eldest son's death in public.

The president has previously faced criticism for embellishing his past, with claims about his involvement in the Civil Rights movement and working in coal mines coming under scrutiny. 

Biden's 1988 campaign for the Democratic presidential nomination also came undone over claims he embellished biographical details for years, including misstatements about his academic record, according to the Washington Examiner. 

However, at this point, the president's misremembering clearly affects how the voters view his ability to serve a second term. 

Poll after poll has shown that Americans are more worried about Biden's age than Trump's.

Only 38 percent of likely 2024 voters believe President Joe Biden will be alive at the end of another four-year term, according to an exclusive poll for DailyMail.com from early April.

And that means one thing: Vice President Kamala Harris is just as likely to be in the top job as Biden come January 2029 if he wins reelection.

J.L. Partners asked 1005 likely voters for their views on Donald Trump and Joe Biden. Only 38 percent said they were confident that Biden would survive four full years of another term

Some 36 percent of likely voters believe Harris will be president at the end of the term. The exact same proportion as think Biden will be in the job.

The results show how the 81-year-old president's age will be a major factor on November 5 when voters pick the commander in chief they want for the next four years.

Donald Trump, his Republican rival, is only four years younger but voters harbor fewer doubts.

More than half say they are confident he will make it through a full term, with 34 percent saying they have doubts.

Either way, the results show how Republicans and Democrats will have to weigh up not just their choice of president but also consider who is likely to step into the breach if ill health—or worse—incapacitates the leader of the free world.
