Presumptive Democratic presidential nominee Joe Biden has a "bizarre" habit of bragging about arrests that never happened, Fox News contributor Mollie Hemingway told "Tucker Carlson Tonight" Monday.

"He’s dreamed of it and thought of it a great deal," Hemingway, senior editor of The Federalist, told host Tucker Carlson.

"And he's had a lifetime of storytelling. I mean, I don't think he's the only politician out there to exaggerate or tell stories but he really is notable for this, and it was something that caused problems for him the first time he ran for president [in 1988] when that candidacy was derailed by his lies, his plagiarism."

BIDEN CONTINUES TO WALK BACK SOUTH AFRICA ARREST COMMENT

In March, Biden was forced to walk back his claim that he was arrested in apartheid-era South Africa three decades ago when trying to visit Nelson Mandela.

The claim was just the latest in the former vice president's string of falsehoods, Hemingway said.

"He adopted a fake persona of a British politician [Neil Kinnock]. He had lied extensively about his academic record," she said. "He has lied about the circumstances of his family's fatal [1972] car wreck that his [first wife, sons and daughter were] in. He lied about whether the person who was involved in that was responsible or whether he was drunk.

"He really has a long track record of lying for personal benefit," Hemingway argued, "and if we had a media that was even remotely careful, they would be talking about this and they would've probably presented these issues to Democratic voters before they chose him in their primary."

In 2008, Biden claimed he was arrested while an undergraduate student at the University of Delaware when he accidentally wandered into a women's dormitory during a trip to Ohio University.

In 2012. Biden clarified his statement, saying that while he wasn't quite arrested, he "almost" was.

"It is interesting and bizarre," Hemingway said.

"One other thing that's interesting is ... he was a really good storyteller," she added. "They weren’t true stories but they were interesting to listen to. Now, when you see him struggling to even respond to these previous falsehoods, he's really having trouble doing it and it's a very interesting to compare, even from 2008 to the current year, what a difference it is and how he is able to tell stories."
