Hunter Biden's lawyers called on federal and state prosecutors across the country to open criminal investigations into his critics on Wednesday, but denied that doing so suggested reports about the laptop's contents are accurate.

Biden's attorney, Abbe Lowell, wrote letters to the Justice Department and the Delaware attorney general calling for investigations into Rudy Giuliani, Steve Bannon and John Mac Isaac, who owns the computer repair shop where Biden is said to have left his laptop. Biden's lawyers also sent cease and desist letters to others who obtained and disseminated the laptop's contents.

Despite the appearances, Lowell argues that Wednesday's letters do not constitute an admission of the laptop's validity. Biden's legal team says the versions of the laptop released to the public may have been tampered with.

"These letters do not confirm Mac Isaac’s or others’ versions of a so-called laptop," Lowell told Fox News Digital. "They address their conduct of seeking, manipulating and disseminating what they allege to be Mr. Biden’s personal data, wherever they claim to have gotten it." 

The DOJ did not immediately respond to a request for comment from Fox News Digital.

Lowell argued in the letters that Mac Isaac and the others had no right to inspect the contents of Biden's laptop, much less make copies of it to share with the media.

"This failed dirty political trick directly resulted in the exposure, exploitation, and manipulation of Mr. Biden’s private and personal information," Lowell wrote in a letter. "Politicians and the news media have used this unlawfully accessed, copied, distributed, and manipulated data to distort the truth and cause harm to Mr. Biden."

The letter went on to accuse Mac Isaac of "theft of computer services," and Giuliani of "possession of stolen property.

"Mr. Mac Isaac chose to work with President Donald Trump’s personal lawyer to weaponize Mr. Biden’s personal computer data against his father, Joseph R. Biden, by unlawfully causing the provision of Mr. Biden’s personal data to the New York Post," Lowell wrote.

The first son's newfound legal aggression comes as Republicans on Capitol Hill are preparing their own investigations into both him and President Biden's family more generally.

An upcoming hearing for the House Oversight Committee will focus on Twitter's censorship of the New York Post's original story on the so-called "laptop from hell," which dropped just weeks before Election Day in 2020.

Other House investigations are expected to focus on Hunter's business dealings. Those investigations are likely to rely heavily on the contents of the laptop.
