Steven Smith told CNN's Michael Holmes that the ship's captain made the announcement over the an internal public address system.
"The captain came on a few minutes ago with another announcement that a helicopter was just dispatched to the ship to drop off some supplies and to pick up a passenger who needed medical attention and they flew that person back to San Francisco," said Smith.
"They do not know what they're going to do, where they're going to have us berth. Right now we don't know what's going to happen tomorrow," Smith went on to say in the interview.
The Grand Princess was on a two-week trip from San Francisco to Hawaii and was scheduled to return Saturday, but has been in quarantine off the coast of California after 21 people were diagnosed with the coronavirus on board.
