The President's 51-year-old son allegedly made the accusations in January 2019.
In a recorded phone call obtained by Daily Mail, the outlet says Hunter bragged to a friend, "I actually smoked crack with Marion Barry I swear to f---ing god."
According to the reports, Hunter claimed it happened when he was a junior in college at Georgetown University.
In the alleged recorded phone call -- which Daily Mail says they obtained from his abandoned laptop -- Joe's son reportedly he'd smoke crack with Barry in a local bar's bathroom.
"He used to come there and drink like late, late. And I would be there, and he would go to the bathroom," Hunter is allegedly heard saying.
Barry died in 2014 at the age of 78.
He also went to prison for 6 months after getting caught smoking crack on camera in a 1990 FBI sting.
Interestingly enough, Hunter wrote in his memoir that being arrested for cocaine possession at 18 "scared him straight'' until after he finished college.
Hunter's abandoned laptop has caused a lot of controversy for his father.
According to a new report, Hunter's leaked emails allegedly prove Joe met with his son's corrupt business partners during a shady dinner while he was Vice President for Barack Obama.
Besides the alleged business dinner, strings of emails, text messages, and x-rated photos allegedly belonging to Hunter have been exposed after Daily Mail obtained a copy of his hard drive.
As Radar reported, Hunter's alleged text messages and emails were recently leaked and showed the close relationship he formed with his former Chinese-American assistant.
She allegedly worked for him when he went into business with a man he reportedly claimed was the "spy chief of China."
