Twitter just added a warning label to a tweet from President Donald Trump that claimed, without evidence, he is immune to coronavirus after his physician cleared him to resume public activities.

“A total and complete sign off from White House Doctors yesterday. That means I can’t get it (immune), and can’t give it. Very nice to know!!!” Trump wrote on Twitter Sunday.
