WSJ: Mueller Subpoenaed the Trump Campaign for Russia-Related Documents

Sending a subpoena to an entity that says it has been cooperating with document requests isn’t unusual in cases in which prosecutors have some concern that their demands aren’t being met promptly or aren’t being entirely fulfilled, former prosecutors said. A subpoena can serve as a backup, to make sure the recipient is complying as promised, and as a reminder that failure to provide documents as demanded would count as obstructing a grand-jury investigation. Mr. Mueller’s team had previously issued subpoenas individually to several top campaign officials, including former campaign chairman Paul Manafort and former national security adviser Mike Flynn. Mr. Manafort currently faces charges including money laundering and tax evasion. He has pleaded not guilty and his attorney has called the charges “ridiculous.”
