The Maine Senate approved a bill from Gov. Janet Mills late Tuesday that would give tribes control of a new sports betting market after a change allowing in-person wagering at a Bangor casino.

The 23-11 vote effectively ensured the measure will go to the Democratic governor for a signature. It is on track to be the biggest overhaul of the state-tribal relationship to pass in 2022 since Mills still opposes a sweeping sovereignty measure preferred by tribes.

It is still a major step for tribes in their quest to renegotiate the terms of a 1980s land-claims settlement in which the tribes accepted tens of millions of dollars in exchange for being regulated like cities and towns.
