Jay-Z and Beyonce may have enjoyed celebrating their five-year wedding anniversary in Cuba last week, but some members of the U.S. Congress are skeptical about how the hip-hop power couple were able to pull off such a trip.

U.S. Representatives Ileana Ros-Lehtinen and Mario Diaz-Balart contacted the U.S. Treasury Department to investigate how the couple was allowed to enter the country considering the ongoing embargo that does not allow Americans to travel there unless they are of Cuban decent or are carriers of a particular license.

In a letter, the two Republican politicians, who both represent areas with large Cuban populations as well as have strong opinions about relations with Cuba, questioned whether or not this trip was a form of "propaganda."

"[It is] very disconcerting that these two mega stars would go down to Cuba and vacation as if they were in a tropical paradise and not say one word about the brutality their hosts display against all pro democracy activists," Ros-Lehtinen wrote.

"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. We represent 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," they also said.

Reuters reports that Bey and Jay's visit was a "people-to-people" visit, and a source claims that the trip was fully licensed by the U.S. Treasury Department. However, the AP claimed they were not aware of the trip. If it is found that they did not file the appropriate paperwork for this trip, they could face $250,000 in fines.
