The eldest son of US President Donald Trump had posted a now-deleted tweet on Tuesday, with a video of doctors talking about the drug hydroxychloroquine.
The video was also taken down by Facebook and YouTube after racking up millions of views, for breaking their rules on COVID-19 misinformation.
The tweets, shared by Mr Trump to his 84 million followers, were deleted as part of Twitter’s enforcement actions.
APIn the misleading video, doctors touted hydroxychloroquine as a cure for COVID-19 and also discounted the need for face masks amid the pandemic.
An article by right-wing news site Breitbart News, which posted the video, included a screenshot counting 17 million video views on Facebook before it was taken down.
