The 51-year-old son of the now-President complained he was using "half his salary" to pay his daddy's bills in a series of shocking leaked emails.
Joe's bills reportedly included $190-per-month for his AT&T phone bill and thousands of dollars in repairs to his home in Wilmington, North Carolina.
The emails seem to cast doubt on Joe's previous claims that he never benefited from Hunter's business deals.
Joe was not short on cash in 2010. He was reportedly earning over $200,000 per year as VP.
At the time, Hunter was working as the CEO of Paradigm Global Advisors. He also sat on the board for the Ukrainian gas company Burisma Holdings.
Despite Joe always claiming he never profited off Hunter's international business affairs, emails seemingly show otherwise.
In leaked messages from his abandoned computer, Hunter spoke to his business partner Eric Schwerin about covering his dad's bills.
The subject read, "JRB bills" -- which most likely stand for Joseph Robinette Biden, Jr.
The email broke down a number of repairs that were done to Joe's lakeside home, including $2,600 on a contractor for a "stone retaining wall."
Hunter also spoke about paying his father's bills in text messages to his daughter, Naomi.
Daily Mail posted the messages showing that Hunter didn't appear happy about the arrangement.
"I hope you all can do what I did and pay for everything for this entire family for 30 years," he wrote to her.
"It’s really hard," he added, "But don’t worry, unlike Pop [Joe], I won’t make you give me half your salary."
Hunter's abandoned laptop has gotten him in plenty of trouble.
Emails, text messages, and damning photos of Joe's son -- who struggled with addiction in his past -- have exposed his party past.
He was allegedly blacklisted from the hotel Chateau Marmont, where John Belushi died, for alleged "drug use."
