On 18 April 2007, the Vigilance and Security Superintendency released a communique rejecting Petro's accusations concerning the CONVIVIR groups. The Superintendency said that many of the groups mentioned were authorized by the Departments of Sucre and Córdoba, but not by the Antioquia government; it also added that Álvaro Uribe, then Antioquia's governor, had eliminated the legal liability of eight CONVIVIR groups in 1997. It was also mentioned that the paramilitary leader known as "Julian Bolívar" had not yet been identified as such and was not associated with any CONVIVIR during the authorization of these groups.[32]
