Senate Democrats introduced new legislation Thursday to hold social media platforms accountable for health-related misinformation during public health emergencies, a move that could cause more censorship during crises similar to the coronavirus pandemic.

The Health Misinformation Act, introduced by Democratic Sens. Amy Klobuchar of Minnesota and Ben Ray Lujan of New Mexico, would amend Section 230 of the Communications Decency Act, the controversial liability shield for user-generated content online. If passed, the legislation would allow social media giants, such as Facebook and YouTube, to be sued for dangerous health misinformation on their platforms.
