Twitter has temporarily halted US President Donald Trump's son from tweeting on its site after he shared a video riddled with unsupported claims about coronavirus.
Many Republicans reacted with outrage, filling social media with cries of "censorship" after Donald Trump Jr's account was put on a timeout for sharing the video, which was viewed millions of times online in a matter of hours, reaching the president himself, before Facebook, Twitter and YouTube banned it.
These social media platforms have zero-tolerance policies on posts that peddle potentially harmful untruths about coronavirus.
Conservative media outlets, pundits and personalities promoted the video across Facebook and Twitter. It features pro-Trump doctors telling Americans they do not need to wear masks to prevent coronavirus while also pitching hydroxychloroquine, an anti-malaria drug the president has previously touted himself, as a way to treat coronavirus.
The video directly contradicts advice from Mr Trump's own medical experts, who have urged people to slow the virus's spread by wearing masks and cautioned against using hydroxychloroquine to treat coronavirus.
The US Food and Drug Administration recently withdrew an order that enabled hydroxychloroquine to be used as an emergency treatment for Covid-19.
Mr Trump's son took to Twitter to share the misleading video with his 5 million followers, calling it a "must watch!!!"
Because it spread misinformation about treating coronavirus, Twitter required Mr Trump Jr to take down the video and put his account on a 12-hour timeout, a Twitter spokesman confirmed.
Mr Trump Jr's profile is still visible, but he cannot tweet, retweet or like other posts during that time.
The president, meanwhile, only retweeted a post of the video, which has since been taken down. His account remains live.
Versions of the video are still circulating widely on platforms like Instagram, Twitter and Facebook, racking up millions of views.
Facebook and Twitter said they have removed several versions and are working to take down others. YouTube also said it has removed the video from its site.
