California begins new lockdown measures as health officials warn of a harsh winter Covid surge
California implemented new lockdown rules and a stay-at-home order. This move comes as coronavirus cases are surging across the United States. Dr. Deborah Birx warned on Sunday that the surge is likely to be the most trying event in U.S. history. "This is not just the worst public health event. This is the worst event that this country will face, not just from a public health side," Birx, the White House coronavirus response coordinator, said on NBC's "Meet the Press."
