Robert F. Kennedy, Sr., may have had a warm friendship with migrant labor leader Cesar Chavez, but there’s no love lost between their sons. When the family of the late labor icon learned that RFK Jr. was using Chavez’s image in his campaign and had planned a rally on Cesar Chavez Day, they told the Los Angeles Times they want the independent candidate to stop appropriating Chavez’s image “for political gain” in the election. “It really prompted us to stand up and to make sure that people understood that the Chavez family does not support his campaign,” Paul Chavez, Cesar’s son, told the Times. The Chavez family has endorsed President Joe Biden, and they say the labor leader would’ve done the same. “When Trump and Kennedy were spreading misinformation about vaccines in the pandemic, people were dying,” Andres Chavez, the labor leader’s grandson, said. “I don’t think my grandfather would stand by anybody who would be spreading this misinformation—knowing that farmworkers and Latinos were among the most impacted.”
