Mr Trump had also shared a string of tweets talking up the abilities of hydroxychloroquine, an anti-malarial drug that the president has championed in the past, to treat Covid-19. Trump Jr. can still browse the site and send direct messages, but he can no longer tweet, retweet, like, or follow new accounts.
In the video, members of the group America's Frontline Doctors promote the drug both as a preventative measure and treatment for Covid-19.
Trump himself, in recent interviews, has described Fauci as "a bit of an alarmist" and accused him of making "mistakes" in his coronavirus guidance. The National Institutes of Health and the Food and Drug Administration have said the drug is not likely to be effective.
The video, featuring what purported to be a press conference from a group of doctors, contained what the platforms said were violations of their policies on COVID-19 misinformation. The video has been taken down from YouTube, Twitter and Facebook after getting more than 14 million views on Facebook.
The president's top trade adviser, Peter Navarro, who has clashed with Fauci over hydroxychloroquine, recently penned a scathing attack on the doctor that was published by USA Today.
The move comes amid growing tensions between the platform and the president.

A speaker who identifies herself as a doctor claims that people do not need to wear masks to avoid coronavirus transmission.
A lab-coated woman in the video claims, "This virus has a cure, it's called hydroxychloroquine, zinc, and Zithromax", and says that masks aren't necessary because this "cure" exists.
Twitter took action because the video violates its policy against posting COVID-19 misinformation.
His account and previous tweets are still visible, but he can not post any further information until he removes the offending tweet, Twitter confirmed.
Trump Jr., in the now-deleted tweet in question, wrote, "This is a much [sic] watch!"
Misleading, harmful claims about Hydroxychloroquine have been promoted by public figures and politicians throughout the pandemic.
