It just occurred to me, what happened to the case before the SCOTUS involving a foreign company fighting a subpoena?
That is a hellava good question!
Found this February 19th update from CNN
Supreme Court ruling means more information on mystery Mueller grand jury case may become public
FTA: Previous unsealing efforts in the courts have revealed that the foreign country and company are represented by the law firm Alston & Bird, that the case subpoena originated with Mueller prosecutors Zainab Ahmad and Scott Meisler and that the DC US Attorney's Office got involved in the appeal.
The name of the country and the company still haven't been revealed.
