Twitter has limited Donald Trump Jr.’s account and deleted one of his tweets for violating Twitter’s COVID-19 misinformation policies.  The tweet, posted on Monday, had what Twitter termed a misleading video on the anti-malarial drug hydroxychloroquine.  An adviser to Trump Jr., Andrew Surabian, tweeted an angry response, in which he said that Trump Jr.’s account had been suspended, adding that “big tech is the biggest threat to free expression in America.”  He added in a statement to Business Insider that Twitter’s action is evidence that “the company is committing election interference to stifle Republican votes.”BREAKING: @Twitter & @jack have suspended @DonaldJTrumpJr for posting a viral video of medical doctors talking about Hydroxychloroquine.Big Tech is the biggest threat to free expression in America today & they’re continuing to engage in open election interference – full stop. pic.twitter.com/7dJbauq43O— Andrew Surabian (@Surabees) July 28, 2020A Twitter spokesman said that the account was not suspended, and instead “Twitter required the tweet to be deleted because it violated our rules” and they merely limited “some account functionality for 12 hours.”  Under limited account functionality, Trump Jr.’s account remains visible and he is able to browse Twitter, but during the 12 hours he is not able to tweet, retweet, or like anything on the micro-blogging platform.
