Anti-vaccine group ambushes medical board president in Walnut Creek

The head of the state medical board that licenses doctors — and promotes vaccines — says that she was surveilled and confronted by an anti-vaccine group in Walnut Creek. Kristina Lawson is an attorney, mother, and former Walnut Creek mayor who is also president of the Medical Board of California. On Monday, Lawson said she was leaving for work when she saw a drone over her Walnut Creek home and a white Ford Expedition parked outside.
