"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.

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 hacked on Sunday, causing the beloved “Sesame Street” character to appear to post expletive-filled antisemitic rants and anti-Trump statements.
