Washington (CNN) Longtime Donald Trump ally Roger Stone is connected to investigations Robert Mueller sent to other prosecutors and that continue despite the special counsel having finished his work, the Justice Department said Friday in a new court filing.

The Justice Department told the federal court in Washington, DC, on Friday afternoon that it shouldn't allow the public release of search warrants being used in Stone's criminal case in DC federal court. The warrants "concern investigations that remain ongoing," the filing says. There's so much sensitive information still in the search warrants that they should not even be released with redactions, the Justice Department argues.

"Because of the interconnected nature of the Special Counsel's investigations, the category of materials here sweeps more broadly than Stone and the specific crimes with which he has been charged," the prosecutors wrote.

"Although the Special Counsel has concluded his investigation, the requested materials concern investigations that remain ongoing, a trial in (Stone's case) that is scheduled for later this year, and the privacy interests of uncharged third parties. No right of public access applies to such materials," the prosecutors said. A media coalition, including CNN, had asked to unseal the Stone warrants.

Prosecutors even gave a hypothetical about ongoing investigations, saying it's possible a defendant gets charged with a crime but still has other conduct and communication with others under investigation.
