Cesar Chavez — the late labor leader and civil rights icon who cofounded the United Farm Workers — is under fire after accusations surfaced he abused young women and minors … with celebrations honoring him now being canceled.

The UFW released a statement Tuesday saying it learned of “deeply troubling allegations” that Chavez “behaved in ways that are incompatible with our organization’s values.”

While some of the reports involve family issues … the org says the “far more troubling” allegations involve abuse of young women and minors. Though UFW says it doesn’t have firsthand knowledge of the allegations, it says they’re serious enough that the org is taking “urgent steps” to learn more and help potential victims.

The Cesar Chavez Foundation says it’s also “deeply shocked and saddened” by the disturbing allegations … which it says involve claims of inappropriate sexual behavior with women and minors while he was president of UFW.
