In 2012, the Green Party of the United States had a platform supporting independence. Socialist Party USA does not support independence for Puerto Rico, but calls for "full representation for the U.S. territories of Guam and Puerto Rico, all Native American reservations, and the District of Columbia." During the summit of the Community of Latin American and Caribbean States in Havana, Cuba in January 2014, Nicolas Maduro, the President of Venezuela, told The Wall Street Journal that he supported Puerto Rican independence, saying that "it's an embarrassment that Latin America and the Caribbean in the 21st century still have colonies. Let the imperial elites of the U.S. say whatever they want." Also at this summit, the president of Argentina, Cristina Fernández de Kirchner, pledged to vote for independence of Puerto Rico; and Raúl Castro "called for an independent Puerto Rico." Other individuals and groups supporting Puerto Rican independence have included: poet Martín Espada, professor and writer Jason Ferreira, the group Calle 13, FALN leader Oscar López Rivera, Roberto Barreto, a member of Organizacion Socialista Internacional; Puerto Rican nationalist Carlos Alberto Torres, and US Representative Luis Gutiérrez. 20th century to present Levinson and Sparrow in their 2005 book suggest the Foraker Act (), and the Jones–Shafroth Act () reduced political opposition in the island, as they vested the U.S. Congress with authority and veto power over any legislation or referendum initiated by Puerto Rico. Founded in 1922, the Puerto Rican Nationalist Party worked for independence. In 1946, Gilberto Concepción de Gracia founded the Puerto Rican Independence Party (PIP). It has continued to participate in the island's electoral process. In the mid-century, the "Cointelpro program" was a project conducted by the United States Federal Bureau of Investigation (FBI) to surveil, infiltrate, discredit, and disrupt domestic political organizations which it classified as suspect or subversive. The police documented thousands of extensive carpetas (files) concerning individuals of all social groups and ages. Approximately 75,000 persons were listed as under political police surveillance. Historians and critics found that the massive surveillance apparatus was directed primarily against Puerto Rico's independence movement. As a result, many independence supporters moved to the Popular Democratic Party to support its opposition to statehood. In the 21st century, a majority of Independentistas seek to achieve independence either through peaceful political means or violent revolutionary actions.
