Donald Trump Jr has been banned from using Twitter for posting "misleading and potentially harmful information" about coronavirus.
The US president also shared the same tweet, however the post no longer appears, and has been replaced with a message indicating that it is "no longer available", but he is still able to tweet.
Trump Jr was suspended for sharing a tweet from Houston-based Doctor Stella Immanuel that falsely claimed there is a cure for Covid-19.
His account and previous tweets are still visible, but he cannot post any further information until he removes the offending tweet, Twitter confirmed.
A spokesman for Twitter said: "The Tweet is in violation of our Covid-19 misinformation policy."
"The account will be locked until the account owner removes the Tweet," the spokesperson added.
The suspension comes amid ongoing tensions between the president and Twitter, over the social media site's approach to his posts.
