“Rob Reiner’s contributions reverberate throughout American culture and society, and he has improved countless lives through his creative work and advocacy fighting for social and economic justice,” Bass added.

California Gov. Gavin Newsom also addressed Reiner’s death, saying he was “heartbroken by the tragic loss.”

“His boundless empathy made his stories timeless, teaching generations how to see goodness and righteousness in others – and encouraging us to dream bigger,” Newsom said in a statement. “Rob will be remembered for his remarkable filmography and for his extraordinary contribution to humanity.”
