Katt Williams made some remarks back in 2019 about diversity and inclusion in Hollywood, suggesting that marginalized voices were not adequately represented in major award ceremonies like the Oscars. His comments were part of a broader conversation about the lack of recognition for artists of color and other underrepresented groups in the industry.

Fast forward to the present, and if something has happened at the Oscars involving John Cena that proves Katt Williams right, I’ll need more context to understand. Could you please provide more details about what occurred at the Oscars involving John Cena?
