Social media platform Twitter barred Donald Trump, Jr. from using most of its features for 12 hours after he tweeted a viral video of doctors holding a press conference in front of the Supreme Court.
In the video, physician members of the group America's Frontline Doctors touted hydroxychloroquine as an effective treatment for coronavirus and disputed the need for the general public to wear face masks.
Sharing the video, Trump Jr. added, "This is a must watch!!! So different from the narrative that everyone is running with."
Twitter has removed tweets containing the video, claiming they violate its policy against misinformation about COVID-19. The company's action against Trump Jr. means he cannot post new tweets nor can he retweet or like any other tweets.
President Donald Trump also retweeted the video Monday, and that tweet was removed. The company did not penalize the president's account.
Responding to the suspension, Andrew Surabian, a spokesperson for the younger Trump, called "Big Tech" "the biggest threat to free expression in America today."
Facebook and YouTube also have removed the video from their platforms.
