President Joe Biden could become embroiled in an FBI investigation of Hunter's finances, experts say, as emails reveal the father and son shared accounts and paid each other's bills. 

Emails recovered by DailyMail.com from Hunter's abandoned laptop between Hunter and Eric Schwerin, his business partner at consultancy Rosemont Seneca, show Schwerin was working on Joe's taxes, discussing the father and son paying each other's household bills, and even fielding requests for a book deal for the then-vice president, as well as managing the donation of Joe's senate papers to the University of Delaware.

It is unclear why Schwerin had this intimate role in the vice president's affairs rather than government officials in the Office of the Vice President.

Hunter's claim that he and his father shared a bank account also raises serious questions whether funds from the alleged joint account were used for Hunter's May 2018 week-long bender with a prostitute in a Hollywood hotel.

Last December, Hunter admitted in a public statement that he was under federal investigation over his tax affairs.

A former federal prosecutor and expert on money laundering and criminal tax law tells DailyMail.com that if money was flowing between Hunter and his father, that could make Joe a target of the probe – but that investigators would have a tough time sitting down with the president.

'Whatever transaction you're looking at, if there's a connection to a family member or a friend, sure the answer is yes [they would be investigated],' the ex-prosecutor, who asked not to be named, said.

'Obviously, if you're talking about the President of the United States, you'd better have a pretty damn good reason to talk to that person.'
