Attorneys involved in the case said their cellphones have been ringing nonstop as they connected with each other, and with reporters, trying to gather more concrete details after a CNN report Friday night that a federal grand jury had approved the first charges in the Russia investigation.

While the report did not cite names, attorneys close to the case said they were discussing whether the indictment was for two known Mueller targets: former campaign chairman Paul Manafort or former White House national security adviser Michael Flynn.

Several attorneys who said they were in touch with the Manafort and Flynn lawyers said they had not been notified of any matter related to an indictment — which is customary in a white-collar criminal investigation — leading them to believe it wasn’t either of those two former high-ranking Trump aides.
