‘President’ Donald Trump on Monday urged caution in admitting people into the U.S. from the Bahamas, claiming ― with no apparent basis in fact ― that “very bad people” could be hidden among the hordes of Hurricane Dorian survivors attempting to flee the devastated archipelago.

“We have to be very careful,” he told reporters outside the White House before heading to a North Carolina campaign rally. “Everyone needs totally proper documentation because the Bahamas had some tremendous problems with people going to the Bahamas who weren’t supposed to be there.”
