With construction of an electronic bingo hall in Aquinnah on indefinite hold, the Wampanoag Tribe of Gay Head (Aquinnah) has petitioned Gov. Charlie Baker to enter into formal negotiations for a full gaming license, including mobile sports betting.

In a Sept. 8 letter to the governor, tribal chairwoman Cheryl Andrews Maltais said she was making an “official request to enter into formal gaming negotiations with the commonwealth of Massachusetts,” as prescribed by the Indian Gaming Rights Act (IGRA). IGRA provides that a tribe that wants to conduct Class III gaming must first enter into a state-tribal compact.

The letter was released Monday by the Aquinnah select board, which had obtained a copy from the governor’s office.
