Since Elon Musk acquired X, formerly known as Twitter, he has received criticism over content moderation policies that allow hate speech. After a recent coding change for X’s artificial intelligence chatbot, Grok reportedly used antisemitic language in its replies. It has since received an update.

The X account of Sesame Street’s Elmo, a beloved children’s television character, shared antisemitic and anti-Donald Trump posts after being hacked on Sunday. A slew of messages calling for the extermination of Jewish people and labeling the United States president a “puppet” of Israeli Prime Minister Benjamin Netanyahu were shared on the account.
