California Gov. Gavin Newsom (D) was back in quarantine Sunday night after coming into contact with a staffer who tested positive for COVID-19, a spokesperson told local media.

"The Governor and staff will be tested again in the next few days," per the statement. Newsom last went into quarantine in November after being exposed to the coronavirus.

Infectious disease expert Anthony Fauci said on Tuesday that if the coronavirus vaccine rollout by the incoming Biden administration goes as planned, the U.S. could start to see effects of herd immunity and normalcy by early-to-mid fall.

What he's saying: "If we [vaccinate] efficiently in April, May, June, July, August, we should have that degree of protection that could get us back to some form of normality. ... But we've also got to do it on a global scale," he said at a Harvard Business Review virtual event.
