Twitter has said that it temporarily blocked US President Donald Trump's official campaign account from tweeting due to a post containing misinformation about Covid-19, AFP reported.

At issue in the post by the @TeamTrump account was a claim by the US president that children are “almost immune” to the novel coronavirus.

The tweet “is in violation of the Twitter rules on Covid-19 misinformation”, a spokesperson for the San Francisco-based service told AFP.

In an extraordinary move, Facebook also took down the same video for “claims that a group of people is immune from COVID-19 which is a violation of our policies around harmful Covid misinformation,” a Facebook spokesperson told AFP.
