Special Counsel Robert Mueller is wrapping up his investigation, planning to release at least partially public memos on Michael Flynn, Michael Cohen and Paul Manafort this week, according to a Monday Yahoo News report.

Though there was some speculation that the Manafort memo specifically would be filed under seal, to keep quiet the additional crimes he committed by lying to prosecutors, Mueller’s office confirmed that it would be largely public, signaling that the investigation has reached a stage where it is unnecessary to hold back information for further indictments.

Per Yahoo News, this impression was further solidified when Mueller gave congressional investigators the go ahead to issue subpoenas to people of interest, which may indicate that Mueller’s team has already talked to everyone of note.

One unnamed source, however, reportedly told Yahoo News that Mueller’s team still asked congressional investigators to steer clear of some witnesses.
