Twitter CEO Jack Dorsey appears to have been hacked on the social media network on Friday afternoon.

A number of tweets, which started slightly before 4:00 p.m. on Friday, began to spread on his personal account.

In a couple particularly egregious tweets, his account tweeted "#N----r" and another said, ""F--k N----rs." The account also retweeted a tweet that read, "nazi germany did nothing wrong." Dorsey's account retweeted numerous other tweets as well. In one, the tweet said, "follow me i am jacks daddy."

"We're aware that @jack was compromised and investigating what happened," Twitter comms tweeted in response to the hack. It's unclear who was responsible for the tweets.

According to The Verge, the hackers appear to be the same group that attacked a group of YouTube creators and influencers including James Charles, Shane Dawson.
