Federal grand jury subpoenas Mashpee Wampanoag Tribe to turn over financial records, sources say Tanner Stening, MassLive · July 14, 2020 at 8:24 pm The Mashpee Wampanoag Tribe, embroiled for years in a complicated legal fight to save its reservation, has been subpoenaed by a federal grand jury to hand over financial records, sources told MassLive. The news was shared with tribe members during a Zoom call on June 23 by attorneys from Todd & Weld LLP, the sources said. The grand jury has requested all records and documents related to the tribe’s finances, they said. It is unclear if individual tribe members were subpoenaed as part of the federal probe. Federal prosecutors told tribe members at the meeting that the “tribe is not the target of the investigation,” the sources said.
