confronted with these allegations to avoid compromising existing operations, but internal CIA communications referred to him as a serious liability. The Church Committee hearings of 1975, which had been triggered by fears that the CIA were running too many rogue operations, had a significant impact on the agency, and Posada's association was seen to be "not in good odor". In February 1976, the CIA officially broke off relations with Posada. Subsequently, Posada made several efforts to get back into the agency's good graces, including informing on an alleged plot by Bosch to kill Henry Kissinger, then US Secretary of State. Coordination of United Revolutionary Organizations Along with Orlando Bosch and Gaspar Jiménez, Posada founded the Coordination of United Revolutionary Organizations (CORU). The group first met in the Dominican Republic in June 1976, and laid plans for more than 50 bombings over the next year. The US Federal Bureau of Investigation (FBI) described CORU as "an anti-Castro terrorist umbrella organization." CORU was responsible for a number of attacks in 1976. These included a machine gun attack on the Cuban embassy in Bogotá, the assassination of a Cuban official in Mérida, Yucatán, the kidnapping of two Cuban embassy employees in Buenos Aires, the bombing of a Cubana airlines office in Panama City, the bombing of the Guyanese embassy in Port of Spain, and the assassination of former Chilean ambassador Orlando Letelier in Washington, D.C. The information Posada provided the CIA while attempting to reestablish good relations with it included a tip that Cuban exiles were planning to blow up a Cuban airliner. Cubana Flight 455 was a Cubana de Aviación flight departing from Barbados, via Trinidad, to Cuba. On October 6, 1976, two time bombs variously described as dynamite or C-4 planted on the Douglas DC-8 aircraft exploded, killing all 73 people on board, including all 25 members of the 1975 Cuban national fencing team. Investigators from Cuba, Venezuela and the United States traced the planting of the bombs to two Venezuelan passengers, Freddy Lugo and Hernán Ricardo Lozano. Both men were employed by Posada at his private detective agency based in Venezuela. A week later, Posada and Bosch were arrested on charges of masterminding the attack, and were jailed in Venezuela. Declassified FBI and CIA reports also show that the agencies suspected his involvement in the airline bombing within days of its occurrence. According to a declassified CIA document dated October
