(CNN) – Two Republican lawmakers are asking a government agency to look into a recent trip to Cuba by Beyoncé and Jay-Z, suggesting the superstar couple violated restrictions on travel to the communist 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. Ileana Ros-Lehtinen and Mario Diaz-Balart, both of Florida, wrote in the letter to the Treasury Department’s Office of Foreign Assets Control.
Beyoncé and Jay-Z were photographed in Havana last week, apparently celebrating their fifth wedding anniversary on the island. While Cuba was a popular getaway for Americans in the 1950s, spending money there was outlawed after Fidel Castro took power in 1959.
In 2012 the Obama administration lifted some of the restrictions on travel to Cuba, instituting a “people-to-people” travel program that requires a strict itinerary for vacationers.
"Each traveler must have a full-time schedule of educational exchange activities that will result in meaningful interaction between the travelers and individuals in Cuba," U.S. Treasury Department guidelines read.
Asked about Beyoncé's and Jay-Z's recent trip, Treasury Department Spokesman John Sullivan said only "I can't comment on specific licenses."
Americans have been known to get around travel restrictions to Cuba in the past by stopping first in a country with flights to the island. Cuban customs officials are familiar enough with the practice to not stamp American passports when they cross their desks.
In their letter the Treasury Department, Ros-Lehtinen and Diaz-Balart noted their connection to “a community of many who have been deeply and personally harmed by the Castro regime’s atrocities, including former political prisoners and the families of murdered innocents.”
“The restrictions on tourism travel are common-sense measures meant to prevent U.S. dollars from supporting a murderous regime that opposes U.S. security interests at every turn and which ruthlessly suppresses the most basic liberties of speech, assembly, and belief,” they wrote. “We support the Cuban people by refusing to sustain their jailers.”
Other lawmakers held different views, such as Republican Sen. Jeff Flake of Arizona.
"So, @Beyonce and Jay-Z @S_C_ are in Cuba? Fine by me. Every American should have the right to travel there," he wrote on Twitter.
