Special counsel Robert Mueller on Thursday filed a request for 70 blank subpoenas in the Eastern District of Virginia, where former Trump campaign chairman Paul Manafort. The two-page filing reveals little, but says that that each subpoena recipient must appear in the Alexandria, Va., courthouse on July 10 to testify in the case. The 70 blank subpoenas amount to 35 total possible subpoenas — in each case, a subpoena is needed for the witness and another is needed for the defense. Court documents filed in April show that Mueller's team was pushing to subpoena 35 witnesses in the trial.
