The Justice Department is proposing legislation to curtail online platforms' legal protections for the content they carry.

The proposal comes nearly three weeks after President Trump signed an executive order to limit protections for social media companies after Twitter began adding fact checks to some of his tweets.

Joe Biden is demanding that Facebook crack down on false information, including from President Trump, adding his voice to escalating criticism over the social network's hands-off approach to political speech.

Russia's trolling specialists have evolved their disinformation and agitation techniques to become subtler and tougher to track, according to new research unveiled on Thursday.

A cache of Instagram posts captured by researchers showed that the Russians were "better at impersonating candidates" and that influence-mongers "have moved away from creating their own fake advocacy groups to mimicking and appropriating the names of actual American groups," wrote Young Mie Kim, a University of Wisconsin professor who analyzed the material with her team.

At the Schweinhaut Senior Center in suburban Maryland, about a dozen seniors gather around iPads and laptops, investigating a suspicious meme of House Speaker Nancy Pelosi.

Plastered over her image, in big, white block letters, a caption reads:

Facebook says it's banning many types of misleading videos from its site, in a push against deepfake content and online misinformation campaigns.

Facebook's new ban targets videos that are manipulated to make it appear someone said words they didn't actually say. The company won't allow videos on its site if they've been either edited or computer-generated in ways that the average person couldn't detect.
