California Gov. Gavin Newsom is warning three counties that they could lose disaster funding if they continue to defy his stay-at-home order. Officials in Yuba, Sutter and Modoc counties have allowed businesses to reopen because they have fewer coronavirus cases than other parts of the state. A spokesman for Yuba and Sutter counties said local leaders are working to do what is best for the overall health of their communities. The letter came Friday as California began the most significant reopening yet of its economy amid the coronavirus pandemic. Under state guidelines, retailers and manufacturers could open with restrictions.
