The U.S. Supreme Court justices expressed skepticism on Wednesday toward a lawsuit against Twitter Inc by the family of a Jordanian man killed in an Istanbul nightclub massacre as they weighed for a second straight day whether to hold internet companies accountable for contentious content posted by users.

American relatives of Nawras Alassaf accused Twitter of aiding and abetting the Islamic State group, which claimed responsibility for the Jan. 1, 2017, attack that killed him and 38 others during a New Year's celebration, by failing to police the social media platform for its accounts or posts.
