A hacker shared a string of racist and antisemitic posts from the social platform X account of Elmo, the fuzzy red monster from “Sesame Street,” the owner and producer of the children’s show said Sunday. The posts, on a verified account with more than 600,000 followers, contained racial slurs, antisemitic language and commentary about President Donald Trump and the so-called Epstein files, the remaining investigative documents of the sex-trafficking investigation into Jeffrey Epstein. The posts were removed shortly after they were published Sunday afternoon. “Elmo’s X account was compromised today by an unknown hacker who posted disgusting messages, including antisemitic and racist posts,” a spokesperson for Sesame Workshop, the nonprofit organization behind “Sesame Street,” said in a brief statement. “We are working to restore full control of the account.” Elmo, the perpetually 3 1/2-year-old beloved Muppet character on “Sesame Street,” often teaches his young audience life lessons like kindness and patience. Elmo’s account had not posted any new messages as of midnight. X could not immediately be contacted for comment. Social media platform X, formerly Twitter, has experienced a surge in racist, antisemitic and other hateful speech since Elon Musk took it over in 2022. Last week, Grok, X’s artificial intelligence chatbot, posted antisemitic comments including praising Adolf Hitler. The company deleted some of the posts and issued an apology. The chatbot’s posts mirrored the “extremist views” of X’s users, xAI, Elon Musk’s artificial intelligence company which created Grok, later said. Experts have recorded a surge in antisemitic and Islamophobic incidents since Hamas led an attack on Israel in 2023 that prompted the Israeli military to invade the Gaza Strip. The Anti-Defamation League, a Jewish advocacy group, recorded 9,354 antisemitic incidents across the United States in 2024, the highest number on record and a 344% increase over the previous five years. These included online incidents in which individuals or groups were harassed on social media or via direct messages, although the organization said it did not attempt to assess the total amount of antisemitism online. “Elevated antisemitism has become a persistent reality for American Jewish communities,” the organization said in its report about the 2024 incidents. In early June, a man threw Molotov cocktails at a Jewish group calling for the release of hostages in Gaza. One of the victims later died of her wounds. Prosecutors charged a man with first-degree murder and a hate crime, among other offenses. The previous month, two employees of the Israeli Embassy in Washington were fatally shot outside an event at the Capital Jewish Museum. A man was later charged with crimes that included first-degree murder. And in April, a man set fire to the Pennsylvania governor’s mansion on the first night of Passover, forcing Gov. Josh Shapiro, who is Jewish, to flee with his family.
