Case 1:18-cr-00032-DLF Document 104 Filed 03/04/19
MOTION FOR A BILL OF PARTICULARS PURSUANT TO FED. R. CRIM. P. 7(f)
Good reading to get a view of the gravamen of Mueller's charge against the Russian Troll Farm.
Most people do not understand the charge. It isn't that the troll farm financed political advocacy ads, that is protected 1st amendment activity. Foreign government are allowed to buy political advocacy ads to influence US elections - that is perfectly legal, provided the entity doing the purchasing registers as an agent of a foreign government. See FARA in general.
This case is a joke, yet the press holds it up as some sort of Mueller success story. People are stupid.
