It seems Elmo's world recently included vitriolic racist and antisemitic social media posts. Sesame Workshop says it seeks to restore control over the beloved puppet's X page.

"Elmo's X account was briefly compromised yesterday by an unknown hacker who posted disgusting messages, including antisemitic and racist posts. The account has since been secured," a spokesperson for Sesame Workshop, the nonprofit educational organization behind Sesame Street, said in a statement to ABC News on Monday.
