The popular X account for the “Sesame Street" character Elmo began posting controversial messages that were quickly deleted after going viral on Sunday.

The posts on Elmo’s account on Sunday called for the extermination of Jewish people, referred to United States President Donald Trump as a “puppet” of Israeli Prime Minister Benjamin Netanyahu and demanded the release of law enforcement files about Epstein, the accused sex trafficker who died in 2019.

"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.
