Facebook and Twitter moved quickly this week to limit the spread of a disputed tabloid story promising new twists in the saga of Joe Biden’s relationship with Ukraine. President Donald Trump's campaign quickly seized on the story in the New York Post — but the report raised more questions than answers, including about the authenticity of an email at the center of the story. Wednesday morning Oct. 14, 2020, hours after the story's publication, a Facebook spokesman tweeted that the company was limiting its distribution on the platform.
