Trump republished a Truth Social message from user Cliff Smith, posted on January 8, that read "Marco Rubio will be president of Cuba," accompanied by a crying laughing emoji.
Trump's comment on the repost was "Sounds good to me!"
The largely unknown user, whose bio refers to him as a "conservative Californian" has less than 500 followers.
Trump's repost comes a week after US forces abducted Venezuela's President Nicolas Maduro and his wife in a nighttime attack in Caracas that killed dozens of Venezuelan and Cuban security forces.
In his own post soon afterwards, Trump said that "Cuba lived, for many years, on large amounts of OIL and MONEY from Venezuela. In return, Cuba provided 'Security Services' for the last two Venezuelan dictators, BUT NOT ANYMORE!"
"Most of those Cubans are DEAD from last week's U.S.A. attack, and Venezuela doesn't need protection anymore from the thugs and extortionists who held them hostage for so many years."
Under a US trade embargo, Havana since 2000 has increasingly relied on Venezuelan oil provided as part of a deal struck with Maduro's predecessor Hugo Chavez.
Trump also urged Cuba to "make a deal" or face unspecified consequences, warning that the flow of Venezuelan oil and money to Havana would now stop.
"THERE WILL BE NO MORE OIL OR MONEY GOING TO CUBA - ZERO!" Trump said. "I strongly suggest they make a deal, BEFORE IT IS TOO LATE."
