MIAMI (CBSMiami) – Superstar Beyonce’ and Jay-Z made headlines last week when they made a surprise trip to Cuba. The trip has drawn the attention of both Congressman Mario Diaz-Balart and Congresswoman Ileana Ros-Lehtinen.

Both representatives have asked the Treasury Department to explain the type of license the super couple received to travel to the Communist nation. U.S. citizens are forbidden to travel to Cuba for mere tourism, though they can get a license for academic, religious, journalistic, or cultural exchange visits.
