5:40 pm: Grand Princess will head to port Monday, crew will be quarantined on ship

California Gov. Gavin Newsom said the Grand Princess cruise ship, which has been idled at sea since Wednesday after passengers previously on board tested positive for COVID-19, will be brought to the port of Oakland some time Monday. The company Carnival's Princess Cruises previously said the ship would be brought to port Sunday, but has since revised the statement.

Newsom said that passengers who are California residents will disembark first and be moved to either local hospitals for immediate medical attention or to 14-day quarantine at a federal facility. Then the remaining passengers will disembark and be taken to Oakland airport, Newsom said, and either be repatriated or flown to one of two federal facilities for quarantine in Texas or Georgia. The more than 1,000 crew members on board the ship, he said, will be quarantined for 14 days on the ship.

Of 46 people tested, 21 have tested positive for COVID-19, Newsom previously said. He added that 788 people have now been tested, though he did not discuss the results of those tests. — Feuer

4:36 pm: White House overruled CDC, official says, did not warn older Americans against flying

The White House overruled health officials who wanted to recommend that elderly and physically fragile Americans be advised not to fly on commercial airlines because of the new coronavirus, a federal official told The Associated Press.

The Centers for Disease Control and Prevention submitted the plan as a way of trying to control the virus, but White House officials ordered the air travel recommendation be removed, said the official who had direct knowledge of the plan. Trump administration officials have since suggested certain people should consider not traveling, but have stopped short of the stronger guidance sought by the CDC.

The person who spoke to the AP on condition of anonymity did not have authorization to talk about the matter. The person did not have direct knowledge about why the decision to kill the language was made or who made the call. —Associated Press
