SACRAMENTO, Calif. (AP) — California's governor has issued stay-at-home orders for 40 million people in the most sweeping move of any state yet to curb the spread of the coronavirus. With half the state already under local stay-home requirements, Gov. Gavin Newsom on Thursday issued a statewide order, warning that unless the rise in cases of COVID-19 slows, it might overwhelm the state’s medical system. Newsom says people will be able to shop for food and seek medical care but should practice social distancing. In a letter to President Donald Trump, Newsom said the virus eventually could infect more than half the state’s population.
