The MNT was invited by the Peronist trade-unions to the CGT's assembly in Rosario in 1964 in order to counter the left-wing. However, in obscure circumstances, gunshots in a closed environment led to the death of two Tacuara activists and one Peronist Youth member. The Tacuaras then retaliated by murdering Raúl Alterman, a Jewish communist chosen only on the basis of his background. This assassination again raised national public outrage, and Joe Baxter, former Tacuara activist who had formed the MNRT, publicly denounced Ezcurra's Nazi ideology on a media show hosted by Bernardo Neustadt. Rodolfo Barra, Justice Minister of Carlos Menem, was forced to resign in 1996 on charges that he had participated to the assassination.
