Eight Southern California Indian tribes have told Gov. Gavin Newsom they plan to begin reopening their casinos May 18, even as the governor pleads with businesses for patience on starting the economy back up.

The chairs of eight gaming tribes in San Diego County laid out their plans to reopen their casinos “with the knowledge that we can maintain and protect the public health and welfare and, if required, scale back if local conditions develop or warrant.” They announced their plans in a letter Friday to Newsom and Greg Cox, chairman of the San Diego County Board of Supervisors.
