The U.S. government may be preparing criminal charges against WikiLeaks boss Julian Assange, according to suggestions in a document filed in an unrelated case.

Assange's name appeared at least twice in papers filed in the Eastern District Court of Virginia, both times appearing to say that Assange has already been made the subject of his own case.

Prosecutors in Virginia say the court document was an error.

The filing alludes to the need to keep paperwork in the case under seal because "due to the sophistication of the defendant and the publicity surrounding the case, no other procedure is likely to keep confidential the fact that Assange has been charged."

It's not clear whether any possible charges against Assange would relate to the probe of Russian interference in the 2016 election or earlier materials that were released by WikiLeaks.

It also isn't clear whether any charges actually have been filed. The Justice Department made no comment about the case.

Assange's lawyer, Barry Pollack, said he hoped federal authorities aren't actually planning to go after Assange.

"The last thing the Department of Justice should be doing is pursuing criminal charges against someone for publishing truthful information," he said.

The court papers' mention of Assange was spotted by terrorism researcher Seamus Hughes.

The exile

Long a thorn in the side of the U.S. government, Assange has spent years hunkered down in the Ecuadorian embassy in London fearing extradition. The lengthy stay was meant to dodge a onetime rape investigation in Sweden — but Assange also has worried about prosecution in the United States.

Assange first grabbed international attention when WikiLeaks began releasing troves of classified documents about a decade ago.

WikiLeaks released secret reports related to the Iraq and Afghan wars. Later, it released a huge archive of sensitive State Department cables that revealed what American diplomats were saying in confidence about leaders and affairs the world over.

Many of those leaks proved embarrassing to the Obama administration, and Chelsea Manning, the former Army soldier responsible for releasing one such trove, initially received 35 years in prison for his role in the matter before President Obama commuted that sentence during his final days in office.

More recently, WikiLeaks played a central role in the campaign of "active measures" waged by the Russian government against the West since 2014.

In 2016, Russian intelligence officers stole emails and other data from scores of political targets in the United States, including the head of the Democratic National Committee and Hillary Clinton's presidential campaign.

Prosecutors allege the military intelligence agency, GRU, then gave this material to WikiLeaks to release throughout 2016. The disclosures cost the job of then-DNC Chairwoman Debbie Wasserman Schultz and embarrassed Clinton's campaign chairman, John Podesta.

Justice Department special counsel Robert Mueller is investigating whether anyone on the Trump campaign conspired with these active measures.

Trump denies there was any collusion and he lashed out at the special counsel's office on Thursday with new condemnations about how it is a "mess" and how the Justice Department is ignoring what he calls transgressions by Democrats.
