A coalition of California Native American tribes sued the state Tuesday seeking more time to qualify a sports betting initiative for the statewide ballot, arguing that the state‘s coronavirus shutdown kept them from collecting voter signatures in recent months.

The lawsuit comes as state officials express concerns that the virus could impede the ability of Californians to go to the polls to vote, leading Gov. Gavin Newsom last month to order ballots to be mailed to the state’s 20.6 million voters.
