had his Twitter temporarily restricted for spreading misinformation about COVID-19?

In a video posted to Twitter and Facebook, Trump claimed that children were “mostly immune” to COVID-19. The videos, part of a campaign to re-open schools across America amid record case and death numbers, was flagged by Twitter and Facebook for misinformation.

Though the suspension was for 12 hours, the video was quickly removed from both platforms and the suspension dropped.

Twitter had taken action against Trump’s misinformation before, including flagging a manipulated video of Biden. He later threatened to leave social media after another tweet was flagged.
