US Cruise Ship Docks in Cuba

A U.S. cruise ship docked in Havana this morning, marking the first time a ship has arrived in Cuba from a U.S. seaport in nearly 40 years.

The Adonia ship, run by Carnival, left from Miami Sunday with about 700 passengers.

People waving Cuban flags greeted the ship as it pulled into Havana today.

The historic trip represents a new step in normalizing U.S.-Cuban relations.
