There have been rumors that a grand jury has already been convened to review the conduct of former Trump campaign manager Paul Manafort and former National Security Adviser Michael Flynn, but this is the first solid report of it.
NBC News reports that "multiple grand jury subpoenas" have been issued for Manafort and Flynn.
Officials say multiple grand jury subpoenas and records requests have been issued in connection with the two men during the past six months in the ongoing probe into whether the Trump campaign colluded with Russian attempts to influence the election, an inquiry that will now be overseen by former FBI Director Robert Mueller.
The FBI, with the help of the Treasury Department, the CIA and other agencies, is examining evidence of possible contacts, money transfers and business relationships between a variety of Trump associates and Russian officials, the sources say.
It's not clear where this may be taking place, and it hasn't been reported at any outlets I feel comfortable citing, but rumors place it at the office of the U.S. Attorney for the Eastern District of Virginia, Dana J. Boente.
Several rumors have been confirmed over the past week, so I'm at least comfortable enough to mention it. At this point, anything feels possible.
A river of dubious cash has flowed through Manafort so it may be months before the results of this investigation are spelled out.
