I never said that! High-tech deception of 'deepfake' videos

Hey, did my congressman really say that? Is that really President Donald Trump on that video, or am I being duped? New technology on the internet lets anyone make videos of real people appearing to say things they've never said. Republicans and Democrats predict this high-tech way of putting words in someone's mouth will become the latest weapon in disinformation wars against the United States and other Western democracies. This technology uses facial mapping and artificial intelligence to produce videos that appear so genuine it's hard to spot the phonies.
