Looks like Mueller is very interested in Paul Manafort, as his home was raided a few weeks ago in the wee hours of the morning:
FOX NEWS – FBI agents raided the Virginia home of Paul Manafort, President Trump’s former campaign chairman in late July, taking documents and other materials related to the investigation into Russia’s meddling in the 2016 election, The Washington Post reported.
Armed with a search warrant, federal agents went to Manafort’s Alexandria home during the predawn hours of July 26 – one day after he met voluntarily with members of the Senate Intelligence Committee.
The search warrant seems to indicate that investigators may have had reason to believe Manafort could not be trusted to turn over all of the records requested in response to a grand jury subpoena, the Post reported, citing people familiar with the special counsel investigation.
Special Counsel Robert Mueller has cranked up the intensity and legal pressure on Manafort on a series of unrelated investigations into various aspects of his personal and professional life.
Remember that Trump fired Manafort last year after news broke that he’d run a pro-Trump campaign in the Ukraine. So who knows what they found after the raid.
