Gov. Gavin Newsom responded Monday to a decision by the U.S. Department of Interior to disapprove class III gaming compacts with two tribes, warning it could have an impact on tribes’ abilities to maintain jobs and investments in their communities.

Tribal-State class III gaming compacts “are agreements between the state and separate tribal governments” that specify how many gaming devices and casinos a single tribe can operate, according to the Tribal Alliance of Sovereign Indian Nations. California has ratified gaming compacts with 75 tribes, and there are currently 66 casinos operated by 63 tribes, according to the California Gambling Control Commission.
