On 17 April 2007, Petro began a debate in Congress about CONVIVIR and the development of paramilitarism in Antioquia Department. During a two-hour speech, he revealed a variety of documents demonstrating the relationship between members of the Colombian military, the current political leadership, narcotraffickers and paramilitary groups. Petro also criticized the actions of Álvaro Uribe as Governor of Antioquia Department during the CONVIVIR years, and presented an old photograph of Álvaro Uribe's brother, Santiago, alongside Colombian drug trafficker Fabio Ochoa Vázquez.[29]
