Gunman Omar Mateen pledged allegiance to the organization in telephone conversations with a 911 operator and police during the rampage that killed 49 at the gay nightclub. Mateen was killed in a shootout with SWAT team members.

A similar lawsuit filed by the victims’ families against the three social media giants was dismissed by a Detroit federal judge last week.

The judge found no connection between social media content and the attack. Another lawsuit against Twitter was dismissed in 2016.
