Facebook on Wednesday took down a video by U.S. President Donald Trump in which he said children are “almost immune” to COVID-19.

The company claimed that the post violated its rules against sharing misinformation about the coronavirus.

“This video includes false claims that a group of people is immune from COVID-19, which is a violation of our policies around harmful COVID misinformation,” a Facebook spokesman said.

He added that it was the first time that the social media company had removed a Trump post for coronavirus misinformation.
