The Grand Princess cruise ship that carries thousands of people, including 21 COVID-19 patients, docked at the Port of Oakland Monday after being held off at sea for days, U.S. Vice President Mike Pence told a media briefing on Monday.

All 25 children aboard are "all healthy," and the 21 people who have been diagnosed with the COVID-19 "are being dealt with in proper isolation," Pence told reporters.

The U.S. has made arrangements with Canada and the UK to take their nations' passengers back through charter flights, he said, and on Tuesday, remaining passengers "will be transported again through carefully controlled environments to military bases in Georgia and Texas," where they will be tested, isolated and quarantined as appropriate.

Pence said he will meet with hospital and health insurance executives on Tuesday.

At the briefing, Pence told reporters that he was unaware if U.S. President Donald Trump had been tested for the novel coronavirus after it emerged that several lawmakers were exposed to the virus before meeting the president.

"We'll refer that question and we will get you an answer from the White House physician very quickly," Pence said.
