During his campaign, Castillo said he would pardon ethnic nationalist Antauro Humala, a ethnocacerist and brother of former President Ollanta Humala, who was sentenced to nineteen years in prison after leading the capture of a police station in Andahuaylas that resulted in the deaths of four policemen and one gunman.[33][34] When concluding his first campaign before the primary round of elections, Castillo held a campaign rally in the Historic Centre of Lima, beginning with a rally at Plaza San Martín, leading a march on horseback to Plaza Dos de Mayo where hundreds of supporters gathered.[3] At the event, he told attendees that if elected, the citizens would supervise his policies, that he would only receive the salary of a teacher and that he sought to reduce the pay for congress and ministers by half.[18]
