The U.S. Supreme Court expressed both skepticism and sympathy for new Republican-backed social media laws regulating content moderation at large internet platforms during a marathon session Wednesday, leaving no clear indication of how it will resolve challenges from the internet industry.

The high court is reviewing the constitutionality of recent laws passed by GOP-controlled legislatures in Florida and Texas to stop what they perceive as the censorship of conservative views by social media platforms. The laws purport to accomplish that goal by restricting the manner in which companies such as Facebook, X and YouTube can take down content that violates their policies.
