Tech mogul and accused fraudster Kim Dotcom is seeking to cut a deal with the U.S. Department of Justice in exchange for his verbal testimony claiming that slain Democratic staffer Seth Rich leaked DNC emails to Wikileaks last summer.

Dotcom – the Mega-upload founder and New Zealand resident who is facing fraud and racketeering charges in the United States – offered to meet with the U.S. special counsel Robert Mueller on Tuesday. He claims to have evidence that Rich, not the Russian government, was behind the DNC email leak last summer.

Dotcom has yet to provide evidence of his allegations, which are fueling internet theories that Rich's unsolved shooting death in Washington, D.C. last July may have been a political assassination. Police believe the 27-year-old was likely killed during an armed robbery gone wrong.

Dotcom is asking the feds to promise not to detain him if he travels to the United States to give testimony about Rich. He is currently facing U.S. extradition from his home in New Zealand on a litany of unrelated charges, including copyright infringement and money laundering.

'[Dotcom] is concerned that, should he travel to the United States voluntarily, he would be arrested and detained in custody on the current counts on which he has been indicted,' wrote his lawyers in the letter to Mueller.

The internet mogul is asking for a deal that 'include[s] arrangements for his safe passage from New Zealand and return.'

The Department of Justice did not respond to request for comment on the letter.

An attorney for Dotcom vehemently denied that the entrepreneur is using the case to try to lessen his legal troubles, in comments to Dailymail.com.

'There will be no part of this deal where his giving of testimony will be conditioned on the United States dismissing the alleged criminal copyright charge against him,' said Dotcom's American attorney Ira Rothken. 'That's not something that's being asked for or contemplated.'

Mueller was recently appointed to investigate allegations of Russian government interference in the presidential election. U.S. intelligence agencies say Russia hacked the DNC servers last summer and handed over the internal emails to Wikileaks.

Although Dotcom's assertions about Rich have drawn international attention – and support from Fox News host Sean Hannity – the internet mogul has provided few details on his sensational story.

Dotcom declined an interview with Dailymail.com, and his attorney said he has no plans to release more information to the public.

In a vague statement posted to his website, Dotcom said he had an online association with Rich for several years and that he 'know[s] Seth Rich was involved in the DNC leak.'

He claims Rich first contacted him online in 2014, using the internet moniker 'Panda' – known to be the DNC staffer's favorite animal.

'Panda' allegedly said he was interested in setting up a U.S. branch of the Dotcom's political party, the Internet Party.

'I now know that Panda was Seth Rich,' said Dotcom. 'I communicated with Panda on a number of topics including corruption and the influence of corporate money in politics.'

Kim Dotcom hinted someone named 'Panda', who he believes was Seth Rich, contacted him about plans to leak DNC documents in 2015. Rich's family have dismissed these claims saying there is not enough evidence to prove this is true

Dotcom hints, but does not specifically state, that 'Panda' informed him of plans to leak DNC documents at some point in 2015.

A spokesperson for Rich's family has dismissed Dotcom's claims, noting that he has produced little to back them up.

The spokesperson told Dailymail.com that Dotcom contacted Rich's family by email recently, but Dotcom never replied when the family asked him to provide documentation of his alleged contacts with Seth Rich.

Dotcom's attorney said the Megaupload founder has no plans to turn over information to the Rich family at the moment.

'To converse with the Rich family at this time would probably be premature,' said Rothken. 'That should be up to the investigators to do from the special counsel's office.'

Rothken declined to say whether Dotcom had any documented evidence to offer outside of his verbal testimony.

'He's offering to give testimony, and in terms of the details, that will have to be discussed at the appropriate time with whoever does the investigation,' said Rothken. 'We're specifically not commenting on the range of materials that could be provided. That will be dealt with properly with the investigators in the special counsel's office.'

In addition to the charges he is currently facing, Dotcom was previously convicted of computer fraud and embezzlement in Germany.

Rich's family implored the public to stop spreading unfounded theories about his murder, after a Fox News article revived speculation about his death earlier this month.

The article, which has since been retracted, stated that the FBI uncovered evidence on Rich's computer showing that he leaked DNC emails to Wikileaks shortly before he was killed.

FBI sources and the Metropolitan Police Department denied the story, and Fox News later retracted it, saying it did not meet its reporting standards.

Dotcom's assertions about 'Panda's' identity yielded mainstream attention through Sean Hannity who spoke about him on his show and retweeted some of his claims

A team of private investigators working on Seth Rich's case also told Dailymail.com that they previously reviewed his emails and did not find evidence that he was in contact with Wikileaks.

Rich was shot in the back twice in the early morning hours of July 10 last year. He had spent the night out at his favorite bar, where staff said he seemed depressed about his rocky relationship with his girlfriend and drank more than usual.

Rich was on the phone with his girlfriend, on a desolate street corner just a couple of blocks from his home in northwest D.C., in the moments before he was shot around 4 a.m. According to investigators, nearby surveillance footage captured grainy images of two men standing near Rich and an ensuing scuffle.

At 4.19am., police responded to the sound of gunshots. They found Rich, wounded but still conscious and talking. The 27-year-old DNC staffer died from blood loss at the hospital two hours later, according to private investigators. His family said he had been excited about a job offer to join the Hillary Clinton presidential campaign.
