Disgusting messages have been posted on his account.
Jack Dorsey, best known as the founder and CEO of social media site Twitter, appears to have had his own personal Twitter account hacked this evening.
Twitter has come under fire over the last few years for its ineffectual approach to removing harmful accounts from the site. It is also famously a favourite media tool of US President Donald Trump.
On Friday evening, it became apparent that Dorsey had been hacked when his account started tweeting racist messages, and retweeting messages such as "Nazi Germany did nothing wrong." His account also tweeted "Intel is there is a bomb at Twitter HQ."
One of the tweets was a racial slur in capital letters.
The tweets have since been removed from the account, though Dorsey has not yet issued a public statement.
It is not yet clear how the perpetrator managed to gain access to Dorsey's account.
