Menem was elected governor of La Rioja in 1973 when the proscription of Peronism was lifted. He was deposed during the 1976 Argentine coup d'état that overthrew President Isabel Martínez de Perón. He was accused of corruption and having links with the guerrillas of the Dirty War. He was detained on 25 March, kept for a week at a local barracks, and then moved to a temporary prison on the ship "33 Orientales" in Buenos Aires. He was detained alongside former ministers Antonio Cafiero, Jorge Taiana, Miguel Unamuno, José Deheza, and Pedro Arrighi, the unionists Jorge Triaca, Diego Ibáñez, and Lorenzo Miguel, the diplomat Jorge Vázquez, the journalist Osvaldo Papaleo, and the former president Raúl Lastiri. He shared a cell with Pedro Eladio Vázquez, Juan Perón's personal physician. During this time he helped the chaplain Lorenzo Lavalle, despite still being a Muslim. In July he was sent to Magdalena, to a permanent prison. His wife Zulema visited him every week, but rejected his conversion to Roman Catholicism. His mother died during the time he was a prisoner, and dictator Jorge Rafael Videla denied his request to attend her funeral. He was released on 29 July 1978, on the condition that he live in a city outside his home province without leaving it. He settled in Mar del Plata.
