Elmo’s account, which has over 650,000 followers and is known for its uplifting child-friendly posts, was taken over by an “unknown hacker” on Sunday, July 13, Sesame Workshop told NBC News in a statement.

Sesame Workshop, which makes the children's show, described the string of antisemitic, racist messages posted to Elmo's X account on Sunday as "disgusting."

Sesame Workshop confirmed in a statement to Variety on Monday morning that the account had in fact been “compromised by an unknown hacker who posted disgusting messages, including antisemitic and racist posts.” The spokesperson confirmed that the “account has since been secured.”
