Tribes are sovereign authorities and not subject to state and local restrictions on operations during the pandemic. Last week, Win-River Resort & Casino in Redding was the first tribal casino to reopen in California after the coronavirus outbreak. The Viejas Casino & Resort was the first of several popular casinos in the San Diego area to open this week. One of California’s largest tribal casinos reopened Monday to a large crowd as customers had their temperatures taken at the door and were ordered to wear facial coverings.
