Twitter said on Wednesday it had restricted US President Donald Trump’s campaign from tweeting after its account shared a video containing false claims about the coronavirus.

The tweet, a video of Trump’s interview with Fox News in which he said children are “almost immune” to the virus, “is in violation of the Twitter Rules on Covid-19 misinformation,” a Twitter spokesperson said in a statement.

“The account owner will be required to remove the Tweet before they can Tweet again.”

The account appeared to have the ability to tweet following Twitter’s statement, suggesting the campaign had complied with the order and removed the video.

Just hours before, Facebook removed a post from Trump’s main page featuring the same interview for similar reasons.

Campaign’s response: Courtney Parella, a spokesperson for the Trump campaign, said the President was “stating a fact that children are less susceptible to the coronavirus,” echoing the statement she shared after Facebook’s removal.

Parella accused Silicon Valley of being biased against the President and said “social media companies are not the arbiters of truth.”

Last week, Twitter imposed a similar restriction on the account of the President’s son, Donald Trump Jr., after he posted a video featuring a doctor making false claims about coronavirus cures and stating that people “don’t need masks” to prevent the virus from spreading.

Twitter said at the time that some of the account’s functionality, including the ability to tweet, would be restricted for 12 hours
