"Chavez fought illegal immigration tenaciously. In 1969, he marched to the Mexican border to protest farmers' use of illegal aliens as strikebreakers. He was joined by Reverend Ralph Abernathy and Senator Walter Mondale. In the mid 1970s, he conducted the “Illegals Campaign” to identify and report illegal workers, “an effort he deemed second in importance only to the boycott” (of produce from non-unionized farms), according to Pawel. She quotes a memo from Chavez that said, “If we can get the illegals out of California, we will win the strike overnight.” The Illegals Campaign didn't just report illegals to the (unresponsive) federal authorities. Cesar sent his cousin, ex-con Manuel Chavez, down to the border to set up a “wet line” (as in “wetbacks”) to do the job the Border Patrol wasn't being allowed to do. Unlike the Minutemen of a few years ago, who arrived at the border with no more than lawn chairs and binoculars, the United Farm Workers patrols were willing to use direct methods when persuasion failed. Housed in a series of tents along the Arizona border, the crews in the wet line sometimes beat up illegals, the “cesarchavistas” employing violence even more widely on the Mexican side of the border to prevent crossings."
