"Anderson was in Washington, and we have proof the tweet was sent from NY, from a phone belonging to his assistant", read the statement.
A few hours ago, Cooper tweeted from his account to say that he "just woke up to find out someone gained access to my Twitter account", with the CNN anchor adding that he had not previously posted anything on Twitter since the weekend.
That's what he's claiming after a Wednesday morning tweet mocking the U.S. President for endorsing failed Alabama Republican Senate candidate (and accused child molester) Roy Moore.
"Oh really? You endorsed him you tool! Pathetic loser", the hacker wrote.
CNN's communications team issued a statement on the social media platform, backing Cooper's claims that someone had gained unauthorized access to his account.More news: Spokesman: Roger Goodell Will Retire As Commissioner After 2023 Season

It's unclear what, if any, safety precautions Cooper was taking prior to the hack.
Donald Trump says he didn't think Roy Moore would win the US Senate election. "Roy worked hard but the deck was stacked against him!"
CNN later released a statement saying that the tweet was made by someone who stole the phone of an assistant to Cooper. According to CNN, someone took possession of the assistant's phone while he was at the gym and sent the tweet. "Anderson was in Washington, and we have proof the tweet was sent from NY, from a phone belonging to his assistant", the statement read.
