Special Counsel Robert Mueller requested that a judge issue subpoenas for 35 witnesses to appear at the trial scheduled in federal court in Virginia for former Trump campaign chairman Paul Manafort, according to a filing dated April 6.

The filing does not say who Mueller intends to subpoena, just that he is requesting that they appear before U.S. District Judge T.S. Ellis when the trial starts July 10.

A separate case brought against Manafort by Mueller is scheduled for trial in Washington D.C. in September. Manafort is facing an assortment of charges of financial crimes, as well as failure to disclose foreign lobbying, stemming from work he did in Ukraine prior to the campaign. He has pleaded not guilty.
