Deepfakes generated by artificial intelligence are having their moment this year, at least when it comes to making it look, or sound, like celebrities did something uncanny. Tom Hanks hawking a dental plan. Pope Francis wearing a stylish puffer jacket. U.S. Sen. Rand Paul sitting on the Capitol steps in a red bathrobe.

Now some U.S. lawmakers are calling on social media platforms X, Facebook and Instagram to explain why they aren’t doing the same.
