The Sonoma County Board of Supervisors is clarifying a controversial provision in the Agricultural Access Verification Program. After a four-and-a-half-hour special session on Tuesday, the board, in a split vote, ruled that the Sonoma County Sheriff’s Office has discretion regarding whether to allow workers to harvest crops, including grapes, in areas under an evacuation order. A large group of farmworkers rallied outside the county administration building as the meeting started. Then later, the public comment period was cut short after about five racist messages were sent to the board via Zoom. It marked at least the third public meeting in Sonoma County to fall victim to a so-called Zoom bombing in the past week.
