On September 23, 2019, speaking on behalf of the Presidency of Andrés Manuel López Obrador, Interior Secretary Olga Sánchez Cordero apologized to Martha Camacho Loaiza, the wife of a leader of the Liga Comunista 23 de septiembre, who was tortured in 1977. The apology took place in the Centro Cultural Tlatelolco, scene of the October 2, 1968 student massacre. This followed a previous investigation by the Presidency of Vicente Fox which ended in charges of genocide against former president Luis Echeverría being dropped.
