Lawmakers on Wednesday questioned what social media companies were doing to respond to threatening posts or messages that can presage acts of gun violence.

Why it matters: Online platforms have become vectors for threats of violence against schools — an issue brought to the fore by the shooting in Parkland, Florida earlier this year. A YouTube user shared the name of the shooter to the FBI, which was later overlooked, after the gunman reportedly left a comment on a video referencing a desire to be a school shooter.
