It turns out the San Manuel Band of Mission Indians, one of the biggest and most influential tribes in California, is the might behind the latest gaming proposal in California.

The tribe’s involvement was revealed Friday when its logo appeared on the letter requesting a title and summary for statewide mobile sports betting initiative from the California attorney general’s office.

News of the initiative broke a week ago when a letter from the Rincon Band of Luiseno Indians, Federated Indians of Graton Rancheria, and the Federated Indians of the Wilton Rancheria came to light. At that time, the San Manuel Tribe wasn’t involved, at least not publicly.
