Superstars Beyonce and Jay-Z generate buzz with virtually everything they do, and their fifth wedding anniversary celebration was no different. 
 
 Marking their anniversary in Cuba last week, they caused a stir when they toured Old Havana, posing for pictures with local schoolchildren and dining at the renowned restaurant La Guarida, where police had to step in to keep the crowds at bay, The Associated Press reported. 
 
 But the visit has also attracted a more critical audience, two Republican congressman from Florida. 
 
 Reps. Ileana Ros-Lehtinen and Mario Diaz-Balart, who represent heavily Cuban districts in South Florida, sent a letter to the federal office responsible for regulating Americans' travel to Cuba asking what kind of license - or special permission - the music power couple had allowing them to travel to the island.

 Unless the U.S. government gives Americans special permission, usually for journalistic, academic, humanitarian or other special reasons that exclude simple tourism, travel to Cuba is prohibited. 
 
 Violations of the government's decades-old embargo governing transactions with and travel to Cuba can result in 10 years in prison and $250,000 in individual fines, according to the U.S. Department of the Treasury. 
 
 In their letter to Adam J. Szubin, the director of the Office of Foreign Assets Control Department of Treasury - the office that issues licenses for permitted trips to Cuba - Ros-Lehtinen and Diaz-Balart wrote: "We write to express concern and to request information regarding the highly publicized trip by U.S. musicians Beyoncé Knowles-Carter (Beyoncé) and Shawn Carter (Jay-Z) to Cuba. We would like to respectfully request, within all applicable rules and guidelines, information regarding the type of license that Beyoncé and Jay-Z received, for what purpose, and who approved such travel."

 The letter added: "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. … 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." 
 
 Rick Klein, political director for ABC News, said, "I think there is going to be a lot of questions for the administration as to how these two very high-profile, very well-connected individuals got to spend their anniversary in Havana." 
 
 A Treasury Department official told ABC News the department does not comment on specific cases. 
 
 Beyonce, 31, and Jay-Z, 43, have also not commented on their trip. ||||| View photo . Singer Beyonce, center holding camera, walks with her husband, rapper Jay-Z, right of her, as they tour Old Havana, … 
 
 
 
 Sure enough , Beyoncé and Jay-Z may have 99 problems but the State Department's Office of Foreign Assets Control (OFAC) Ain't One. 
 
 OFAC, which enforces sanctions against Cuba, assured Republican Representatives Mario Diaz-Balart and Ileana Ros-Lehtinen in a letter Tuesday that the pop power-duo's recent trip to the island on their fifth anniversary had the governmental green light. The Florida lawmakers had written to the Treasury Department demanding to know whether the trip fell afoul of Cold War-era restrictions on Americans' travel to Cuba. 
 
 "It is our understanding that the travelers in question traveled to Cuba pursuant to an educational exchange trip organized by a group authorized by OFAC to sponsor and organize programs to promote people-to-people contact in Cuba," Alastair Fitzpayne, Assistant Treasury Secretary for Legislative Affairs, wrote in the letter, which was obtained by Yahoo News. 
 
 Fitzpayne, however, also seemed to put a little distance between OFAC and the globetrotting couple, who gave vast sums to President Barack Obama's reelection campaign. He noted that "organizations holding people-to-people licenses must certify in writing to OFAC that any travel that they conduct will consist of a full-time schedule of educational activities that will result in meaningful interaction between the travelers and individuals in Cuba." 
 
 But OFAC "does not request the identities of the travelers on each trip," he said. 
 
 Ros-Lehtinen was unimpressed. 
 
 "If the tourist activities undertaken by Beyonce and Jay-Z in Cuba are classified as an educational exchange trip, then it is clear that the Obama Administration is not serious about denying the Castro regime an economic lifeline that US tourism will extend to it," the Cuban-born lawmaker said in a statement. 
 
 "That was a wedding anniversary vacation that was not even disguised as a cultural program," Ros-Lehtinen said. "As more human rights activists engage in hunger strikes, I don't think they will see any evidence of how this scam endeavor will help them become independent of the regime." 
 
 If you’re inclined to dig through Treasury's regulations, here they are, but it’s probably enough to say that, as part of a 60-year-old embargo imposed after Fidel Castro seized power, Americans aren’t supposed to go there. And lawmakers like Ros-Lehtinen and Diaz-Balart have denounced tourism in Cuba because it provides the Communist government there with sorely needed foreign currency. 
 
 The embargo, first imposed by Dwight Eisenhower in 1960 and tightened by many of his successors, aimed to punish Castro’s government for nationalizing U.S. property, to dissuade other Latin American countries from following in Castro’s revolutionary footsteps, and, ultimately, to drive Castro from power. 
 
 Tourism to Cuba -- notably from Europe and Canada -- has increased over the years as the island has seen the development of luxury hotels. Americans have been going there in larger numbers as well, and advice on how to go there illegally has proliferated online. With the Soviet Union long gone, Americans have also softened their support for the embargo. 
 
 That's not to say that everyone approves. In March, Republican Senator Marco Rubio ripped American visitors to Cuba. "Cuba is not a zoo where you pay an admission ticket and you go in and you get to watch people living in cages to see how they are suffering," Rubio said in a speech. ||||| Beyonce and Jay-Z are being criticized for spending their fifth anniversary in Cuba. 
 
 Mauricio Claver-Carone, the Executive Director of Cuba Democracy Advocates in Washington, D.C., a group dedicated to promoting democracy in the Caribbean country, blasted the hip-hop power couple for vacationing in the communist nation. 
 
 "There are women getting beaten on a daily basis, women who are being jailed for no reason ... people are fighting for their freedom," he told TMZ, claiming Beyonce and Jay-Z's failed to educate themselves on Cuba's human rights violations before making the trip. "It’s extremely insensitive," he added. 
 
 News of the visit spread when Beyonce and Jay-Z were photographed in Havana earlier this week, dining at local restaurants and touring historical locations. But it remains unclear why they chose to visit the region to celebrate their April 4 wedding anniversary. 
 
 The Associated Press notes America's 51-year embargo makes it illegal for U.S. citizens to travel to Cuba solely for tourism. Travelers can visit the country legally by obtaining a "cultural exchange" license, however. 
 
 The U.S. Treasury Department's Office of Foreign Assets Control, which approves travel to the country, would not comment on Beyonce and Jay-Z's individual case. 
 
 This is not the first time the "Love On Top" singer has offended in recent weeks. 
 
 When Beyonce, who has recently referred to herself as a "modern day feminist," released her newest single, "Bow Down/I Been On," on March 17, she was criticized for the song's seemingly misogynistic lyrics.

– Two Florida lawmakers want to know why Beyonce and Jay-Z were celebrating their fifth wedding anniversary in Cuba—where most Americans are still forbidden to travel, CNN reports. "Numerous press reports described the couple’s trip as tourism, and the Castro regime touted it as such in its propaganda," wrote Reps. Ileana Ros-Lehtinen and Mario Diaz-Balart, both Republicans, in a letter to the Treasury Department. The lawmakers called for a Treasury agency to investigate the visit. Mauricio Claver-Carone, the head of a PAC that promotes democracy in Cuba, added to the outcry: "There are women getting beaten on a daily basis, women who are being jailed for no reason ... people are fighting for their freedom," he told TMZ. "It’s extremely insensitive." A US embargo makes it illegal for Americans to visit Cuba without a "cultural exchange" license, but many still go there from neighboring countries, the Huffington Post reports. Maybe that's how the high-powered pair got to Havana, where they set off flashbulbs as they dined in restaurants and visited historical sites.
