The cases are among several the justices have grappled with over the past year involving social media platforms. Next month, the court will hear an appeal from Louisiana, Missouri and other parties accusing administration officials of pressuring social media companies to silence conservative points of view. Two more cases awaiting decision concern whether public officials can block critics from commenting on their social media accounts, an issue that previously came up in a case involving then-President Donald Trump. The court dismissed the Trump case when his presidential term ended in January 2021.
