Members of the U.S. House of Representatives are attempting to keep U.S. citizens from traveling to Cuba.

On Tuesday, a House Department of Transportation appropriations bill was introduced. One of the provisions barred the use of funds to facilitate any new air transportation originating from the U.S. if any of the flights pass through or land on property confiscated by the Cuban government. 

According to Reuters, the bill also included a passage barring the use of any funds covered in the bill to issue licenses or operating certificates for vessels that docked within seven miles of any property that had been confiscated by the Cuban government within the previous 180 days.

As reported in the Miami Herald, cigars, which fall under restricted amounts of goods, would still be imported. 

Representative Mario Diaz-Balart, who introduced the bill, said in a statement: "U.S. law prohibits tourism in Cuba, and U.S. law also allows for those whose properties were confiscated by the Castro regime to sue those who use, or benefit from using, those confiscated properties.”

Diaz-Balart, a Cuban-American Republican who hails from Florida, is a vocal opponent of Obama's effort to ease U.S. relations with the communist country.

Back in December, Obama announced he would move the U.S. toward more normal relations with Cuba, which to many meant the ability to travel freely between the two countries.

Obama’s announcement was met with heavy resistance from many members of Congress, most notably Republicans that by and large contended that Cuba would first have to make some human rights changes and send back any U.S. fugitives harbored there to face trial, before Washington should begin to ease up on trade restrictions.
