Misinformation spikes as Trump confirms COVID-19 diagnosis

CHICAGO (AP) — News Friday that President Donald Trump and first lady Melania Trump had tested positive for COVID-19 sparked an explosion of rumors, misinformation and conspiracy theories that in a matter of hours littered the social media feeds of many Americans.

Tweets shared thousands of times claimed Democrats might have somehow intentionally infected the president with the coronavirus during the debates.

This is both a political crisis weeks before the election and also a health crisis; it’s a perfect storm,” said Alexandra Cirone, an assistant professor at Cornell University who studies the effect of misinformation on government.

Facebook said Friday that it immediately began monitoring misinformation around the president’s diagnosis and had started applying fact checks to some false posts.

Twitter, meanwhile, was monitoring an uptick in “copypasta” campaigns about Trump’s illness. “Copypasta” campaigns are attempts by numerous Twitter accounts to parrot the same phrase over and over to inundate users with messaging, and they are sometimes signals of coordinated activity. The social media company said it was working to limit views on those tweets.  ...
