Senator Marco Rubio from Florida is spending his Tuesday at Guantanamo Bay at the U.S. Naval Base. Rubio’s parents are originally from Cuba and left the island nation in 1956. This will be the first time the young Florida Senator has been to Cuba. Rubio is a member of the Senate’s Select Committee on Intelligence and will spend all day on the base to get a better understanding of what the operations are there.

Senator Rubio will remain on base property for his entire stay, which the government of the U.S. leases from Cuban officials and uses as one of their Caribbean Naval Bases. A prison located on the base houses hundreds of detainees that the government of the U.S. labels enemy combatants. Most of them were captured after the attacks on the Pentagon and New York by al-Qaeda.

Rubio has expressed concern at Intelligence Committee meetings about the detainee’s activities after they are released. He co-sponsored a piece of legislation in 2011 that would make sure the prison stays open.

While at the base, Rubio will receive a complete tour of the facility and meet the commander in charge of the base. This will allow the Senator to learn the role the base plays in the detention operations for the U.S.

Rubio also will tour the area where military tribunals are held from detainees. The Expeditionary Legal Complex, where the tribunals are held is a secure location to try the detainees that are charged by the U.S. government. It allows for full access to both sensitive and classified documents, to prosecution and defense lawyers and full access by the media.

One of Rubio’s last places to visit before returning to the U.S. will be Camp IV, the building that houses the detainees.
