Twitter Inc said on Tuesday it had reined in access to Donald Trump Jr's account for 12 hours because a tweet he had posted violated the social media site's misinformation policy on COVID-19.
The eldest son of U.S. President Donald Trump had posted a video on Monday of doctors talking about the drug hydroxychloroquine, that was removed by Twitter.
The video was also taken down by Facebook Inc and Alphabet Inc-owned YouTube after racking up millions of views, for breaking their rules on COVID-19 misinformation.
President Trump also retweeted a post late on Monday containing a link to the video and accusing Dr. Anthony Fauci, the nation's top infectious disease expert, and Democrats of suppressing the use of the drug hydroxychloroquine to treat the novel coronavirus.
The tweets shared by Trump were deleted as part of Twitter's enforcement actions archive.
Fauci, who directs the National Institute of Allergy and Infectious Diseases (NIAID) and has worked under six U.S. presidents, said on Tuesday he has "not been misleading the American public under any circumstances."
The U.S. Food and Drug Administration last month revoked its emergency-use authorization for hydroxychloroquine to treat COVID-19, the illness caused by the novel coronavirus, after several studies cast doubt on its effectiveness. Trump has regularly touted the drug and said he has used it himself.
In the video, the doctors also discounted the need for face masks amid the pandemic.
The White House did not immediately respond to a Reuters request for comment.
"It is beyond the pale for Twitter to silence someone for sharing the views of medical professionals who happen to dissent with their anti-hydroxychloroquine narrative," said Andy Surabian, a spokesman for the president's son, after sharing a screenshot that said Twitter had temporarily limited @DonaldJTrumpJr's ability to tweet, retweet or like content.
"We did not suspend the account. The screenshot shared directly says that Twitter required the Tweet to be deleted because it violated our rules, and that we would limit some account functionality for 12 hours," a Twitter spokesman told Reuters.
