CNN has released a statement claiming that a tweet sent from Anderson Cooper’s account calling Trump a “pathetic loser” was sent from the phone of Cooper’s assistant, who had left the device unsupervised at his gym.

BuzzFeed News reports that following a tweet sent out by CNN pundit Anderson Cooper which called President Trump a “pathetic loser,” the news station has issued a statement claiming that it was not Cooper who had sent the tweet but a member of the gym attended by Cooper’s assistant. The initial tweet sent from Cooper’s account was in reply to President Trump’s tweet about Roy Moore’s general election loss in Alabama.

A reply from Cooper’s Twitter account stated, “Oh Really? You endorsed him you tool! Pathetic loser.” This tweet was deleted a few hours later, and a second tweet was posted by Cooper stating that someone had “gained access” to his account and that he has “not sent a tweet in days.” Cooper said that CNN was investigating how the tweet had been sent from his account,

Many were quick to jump to Cooper’s defense after the initial tweet was posted, including CNN’s Andrew Kaczynski who runs the news agency’s KFILE department which is allegedly the “leading investigation team for the social, mobile generation,” but even Kaczynski claimed to have no knowledge of how the initial tweet was posted.

Other Twitter users were quick to ridicule the tweet.

A CNN spokesperson then revealed in a statement to BuzzFeed News that the tweet had been sent from Cooper’s assistant’s phone by someone attending his gym. CNN did not speculate how the third party gained access to the phone. Smartphones are frequently locked with a passcode or fingerprint ID.

Twitter users were also quick to ridicule this explanation from CNN.

This is currently the only official statement by CNN explaining the tweet sent from Anderson’s account.
