President Donald Trump on Wednesday called Puerto Rico "one of the most corrupt places on earth" as the U.S. territory prepared for a hit by Tropical Storm Dorian, which brought back memories on the island of devastation from hurricanes two years ago.

Puerto Rico is still struggling to recover from back-to-back hurricanes in 2017, which killed about 3,000 people just months after it filed for bankruptcy.

Dorian was bearing down on Puerto Rico from the southeast and was expected to become a hurricane soon as it barrels toward Florida, which it could hit as a major hurricane.
