 Between September and December, Chavez travelled the country in a Winnebago speaking at dozens of fundraisers and rallies for the grape boycott.At a speech in Washington D.C., he came out publicly against U.S. involvement in the Vietnam War, a topic he had previously avoided speaking on, because his son Fernando had been arrested as a conscientious objector.In the late 1970s, Chavez also sought to advance his control over the California Rural Legal Assistance (CRLA), a group which advocated for farmworkers.
