which he did without consulting Barceló. The successes of Muñoz Marín convinced many in the island that he was the true leader of the Liberal Party, thereby creating a faction within the party between those who considered Muñoz Marín the true leader and those who considered Barceló as their leader. After the assassination of police colonel Francis Riggs in San Juan as an indirect result of the Río Piedras massacre, which involved the police and students of the University of Puerto Rico, U.S. Senator Millard Tydings presented a legislative proposal in 1936 to grant independence to Puerto Rico. Barceló and the Liberal Party favored the bill, as did other Puerto Rican parties of the time, because it would give Puerto Rico its independence; Muñoz Marín opposed the bill because he thought it had unfavorable economic conditions. In 1936, a party assembly was held in San Juan where Muñoz Marín stated that he was not interested in being considered for the position of Resident Commissioner and that Barceló should be the Commissioner. This move would leave the presidency of the party empty and open for Muñoz Marín. Barceló refused to be named Commissioner and to relinquish his presidency. Muñoz Marín and his followers founded a group within the party called "Accion Social Puertorriqueño" (Puerto Rican Social Action) who believed in the immediate independence of Puerto Rico. After the Liberal Party was defeated in 1936 elections, an assembly was held in Naranjales on May 31, 1937, in which Muñoz Marín presented his ideas as to how the party should be run; however, the majority of the party members objected and blamed him for their defeat. Muñoz Marín considered this action the same as having been expelled from the party. Muñoz Marín and his followers, among which were included Felisa Rincon de Gautier and Ernesto Ramos Antonini, held an assembly in the town of Arecibo, founded the Clear, Net, Authentic, and Complete Liberal Party (Partido Liberal, Neto, Auténtico y Completo), claiming to be the true Liberal Party.

Maria Antonia Josefina Barceló was elected president of the Liberal
