President Donald Trump’s event is scheduled for Friday afternoon at the Manuel Artime Theater at 900 S.W. 1st Street. Vice President Mike Pence and Secretary of State Rex Tillerson were in town on Thursday.

The president is making good on a campaign promise to modify the relationship between the U.S. and Cuba. Florida Sen. Marco Rubio has bent Trump’s ear on making the change.

“Suffice to say, tomorrow will be a good day and a better deal for the Cuban people, by empowering them and doing so in a way that we do not empower their oppressors,” Rubio said.

On Friday, President Trump will announce a slew of changes, including a ban on Americans doing business with any group associated with the Cuban military regime and restricting travel to specific and well-documented reasons. Money exchanges between the countries will remain intact.

“Many of the hotels, many of the entire tourism infrastructure in Cuba is controlled by the military. It is a way of raising funds for the military which is also in charge of repression, keeping Cubans down to keep Castro’s in power,” said local Cuban activist Orlando Guiterez.
