A newspaper claims Ted Cruz's father helped Lee Harvey Oswald distribute leaflets promoting Fidel Castro's communist regime in 1963. The National Enquirer published photos of John F Kennedy's killer, claiming to have concrete evidence the man beside him (circled in red) is Cuba-born Rafael Cruz. The images, released by the US government amid an investigation into JFK's assassination, show Oswald (far right in the black-and-white photo) and a group walking around a street in New Orleans handing out leaflets to passers-by. They were used as evidence against New Orleans-based Oswald, who was murdered by Jack Ruby days after the Dallas shooting, in an investigation into the president's death. But the man in the white shirt beside him was never identified. It would not be the first link between the elder Cruz and Castro; Ted admitted last year that his father tried to join Castro's guerrilla army during the 1950s revolution which overthrew the Batista regime in 1959. But he has never been linked to Oswald. The Cruz campaign has flatly denied the Enquirer's claims.
