There's another warning from President Donald Trump to Cuba in the wake of Nicolás Maduro's ouster in Venezuela. Cuba is a close ally of Venezuela and a major beneficiary of oil shipments from Venezuela. But Cuba has been cut off from shipments as U.S. forces seize tankers. Trump used a social media post Sunday to urge Cuba to make a deal before, as he put it, “IT IS TOO LATE.” He didn't explain what kind of deal. Cuba's president responding by saying “those who turn everything into a business, even human lives, have no moral authority to point the finger at Cuba in any way.”
