Late Monday evening, the president retweeted complaints about the video being removed, praised hydroxychloroquine and criticized Anthony Fauci, the top USA infectious disease expert, for contending that the drug isn't an effective treatment for COVID-19.
In the video, the individuals said, "you don't need masks" to prevent the spread of COVID-19.
The eldest son of U.S. President Donald Trump had posted a now-deleted tweet on Monday, with a video of doctors talking about the drug hydroxychloroquine.
The latest salvo in the battle to control online information is a group calling itself "America's Frontline Doctors".
Immanuel's claims are contrary to the extensive tests that have been done regarding the drug. The US Food and Drug administration has deemed the drug as ineffective in treating the virus, and medical experts have repeatedly warned against using it.
A spokesman for Twitter said: "The Tweet is in violation of our Covid-19 misinformation policy". Fauci said on ABC's "Good Morning America". Earlier in the pandemic, the president advocated for hydroxychloroquine to be used as a treatment, or even a preventative, according to AP. The video has been taken down from YouTube, Twitter and Facebook after getting more than 14 million views on Facebook. Trump Jr.'s profile is still visible, but he can not tweet, retweet or like other posts during that time. On YouTube, a video from the event received 80,000 views before being removed by the platform for "violating YouTube's Community Guidelines".
It said: "This account has not been permanently suspended".
To end the "lockout", Trump Jr. must willingly delete the tweet himself.
"I put them on hydroxychloroquine, I put them on zinc, I put them on Zithromax, and they're all well".
Facebook and Twitter have taken down a viral video retweeted by Donald Trump which claims that Dr Anthony Fauci misled the country on hydroxychloroquine.
The doctors also backed the use of hydroxychloroquine, an antimalarial drug that has not been proved effective against COVID-19. We only wear surgical mask.
Others in the video claimed that "many thousands of physicians [have] been silenced", that hydroxychloroquine and chloroquine are "the same", and the coronavirus "is not that novel" although the virus has never been seen in humans before.
More than 4 million people in the USA have been infected by the coronavirus and the death toll is nearing 150,000, according to a tally by Johns Hopkins University.
