Claims Biden accidentally called Trump 'George' fact-checked as 'misleading'

US President Donald Trump has mocked rival Joe Biden claiming he accidentally called him "George" during an interview, but fact-checkers have weighed in calling the claims "misleading".

"Joe Biden called me George yesterday," read one of Trump's Twitter posts, a platform he regularly uses to insult political opponents.

"Couldn't remember my name. Got some help from the anchor to get him through the interview. 

"The Fake News Cartel is working overtime to cover it up."

Trump was referring to an interview with Biden at a virtual concert 'I Will Vote' at the weekend, where he stuttered mid-sentence.

"What kind of country are we going to be? Four more years of George, err, George... we're going to find ourselves in a position where Trump gets elected, we're going to be in a different world," Biden said.

But after Trump called Biden out for "calling me George", fact-checks by US news sites including The Washington Post and The Wrap have revealed the claims are "misleading" - it turns out the concert was being hosted by George Lopez and was the one interviewing Biden, but wasn't in shot when he made the statement.

"By beginning the clip after the moderators were removed from the screen, viewers have no idea that Biden could have been referring to Lopez who had originally asked the question," The Post says.

Andrew Bates, a spokesman for Biden, said the Democratic nominee was addressing Lopez.

"That is, unless, like Donald Trump, you blow a gasket and storm out because you can't stomach being fact-checked," Bates told The Post.

But a Republican who also claimed on Twitter that Biden "confused President Trump with George W Bush", Steve Guest, accused the newspaper of "doing the Biden campaign's bidding to cover up" what the Democratic nominee said.

"Biden was talking about 'four more years' of President Trump and said the name 'George' instead.

"His wife is mouthing 'Trump' next to him in an attempt to save him and remind him who is currently President," Guest said in a statement to Post fact-checker Meg Kelly.

Twitter in the past few months has censored or removed several of Trump's posts due to breaking its rules of making false or misleading claims.

But the post about Biden has not been censored by Twitter. 

Facebook, where the post was also shared, has not flagged it with its "get voting information" disclaimer, as is standard with the majority of Trump's political posts.
