Unless Whitaker steps in to stop it?

Special counsel Robert Mueller’s prosecutors have told defense lawyers in recent weeks that they are “tying up loose ends” in their investigation, providing the clearest clues yet that the long-running probe into Russia’s interference in the 2016 election may be coming to its climax, potentially in the next few weeks, according to multiple sources close to the matter.

Or, tying up loose ends could take a while.

The new information about the state of Mueller’s investigation comes during a pivotal week when the special counsel’s prosecutors are planning to file memos about three of their most high profile defendants — former Trump national security adviser Michael Flynn, former Trump campaign chairman Paul Manafort and former Trump personal lawyer Michael Cohen.

That at least seems to indicate they're through getting whatever information they think they need from those three.

A Flynn sentencing memo is due Tuesday, and memos about Manafort and Cohen are slated for Friday. All three documents are expected to yield significant new details on what cooperation the three of them provided to the Russia investigation.

Peter Carr, spokesman for the special counsel, confirmed to Yahoo News on Monday that the Manafort memo “will be public,” although he added there could be some portions that are redacted or filed as a sealed addendum.

“What we were told is that the investigation has reached a mature enough stage that they’ve basically talked to everybody they want to talk to,” said a knowledgeable source who asked not to be identified because of the sensitivity of the matter.

Mueller’s office declined any public comment when asked to confirm that account, leaving open the possibility that there still could be a few witnesses yet to be questioned. Another source indicated that Mueller’s office is still asking congressional investigators to stay away from some other witnesses.

...but hey, do what you want...you will anyway.
