Hours after House Speaker Nancy Pelosi addressed a conference Wednesday, a distorted video of the California Democrat’s conversation began spreading across the internet. The manipulated clip, slowed to make Pelosi sound as if she were slurring her words, racked up millions of views on Facebook the following day. It was posted to YouTube, and on Thursday night was given a boost on Twitter when Rudy Giuliani, President Trump’s personal lawyer and former mayor of New York, shared a link with his 318,000 followers. Sam Dean and Suhauna Hussain write in the Los Angeles Times that by Friday, the three social media giants were forced to respond to this viral instance of political fakery. How they dealt with the issue, three years after being blindsided by a wave of fake news and disinformation in the 2016 election cycle, may serve as a harbinger of what’s to come in 2020.
