US President Barack Obama tours the Bob Marley Museum led by tour guide Natasha Clark (3rd-L) in Kingston, Jamaica on April 8, 2015. Obama, the first sitting US president to set foot on the island since 1982, is in the country to meet with a regional block of Caribbean nations and possibly offer them an alternative to cheap Venezuelan oil amid a spat with Caracas. He heads late April 9th to Panama, where he may have a landmark meeting with Cuba's communist President Raul Castro. AFP PHOTO / MANDEL NGAN (Photo credit should read MANDEL NGAN/AFP/Getty Images)
