A University of Miami professor compared Jay-Z and Beyonce celebrating their wedding anniversary in Cuba to visiting Nazi Germany to enjoy Adolf Hitler.

"I feel disgusted," said Dr. Jaime Suchlicki, the former director of the University of Miami's Research Institute for Cuban Studies. "Very few people went to Nazi Germany to enjoy Hitler."

"It's not a place to have a vacation," said U.S. Rep. Ileana Ros-Lehtinen. "They have to know that they're going to be used by the Cuban regime to try to portray a sense of normalcy on the island."

"Despite the clear prohibition against tourism in Cuba, numerous press reports described the couple's trip as tourism, and the Castro regime touted it as such in its propaganda," Reps. Ros-Lehtinen and Mario Diaz-Balart wrote in the letter to the Treasury Department's Office of Foreign Assets Control.

The couple had a license to travel to Cuba for cultural purposes, according to the Treasury Department.

"You can go to Cuba as an American if you're going with a religious group, with a humanitarian group, or with a cultural group," said Suchlicki.

"Pay attention to what human rights abuses are occurring in the very island where you're partying," added Ros-Lehtinen.
