He supported the 1965 farm worker movement with Cesar Chavez in Delano, California. Sheen endorsed marches and walkouts called by the activist group By Any Means Necessary (BAMN) to force the State of California to introduce a holiday in memory of Cesar Chavez. On the day of the protests (March 30), thousands of students, primarily Latino from California and elsewhere, walked out of school in support of the demand. Sheen also stated that he participated in the large-scale immigration marches in Los Angeles in 2006 and 2007.
