Jack Dorsey's Twitter account was hacked by a group that refers to itself as "Chuckle Squad."
The compromised account displayed a series of aggressive and offensive tweets, including messages with the N-word, one that defended Adolf Hitler, and another that threatened to blow up Twitter's headquarters.
The group also invited Dorsey's followers to join their Discord server and "Chuckle with us."
The hackers' tweets have since been removed from Dorsey's account.
The accounts that were retweeted during the hack have also been suspended.
