Cuban dissidents Samuel Rodiles, Felix Navarro, Berta Soler, Guillermo Farinas, Angel Moya and Egberto Escobedo (L-R) attend a news conference in Havana January 23, 2015. U.S. Assistant Secretary of State Roberta Jacobson, the highest-ranking U.S. government official to visit the island in nearly 40 years, met this group of dissidents on Friday, seeking to underline Washington's concern over human rights but irritating the island's communist government.
