Six more families related to victims of the 2012 Sandy Hook Elementary School shooting filed a defamation lawsuit against radio personality Alex Jones on Wednesday.
The families are joined by an FBI agent who responded to the shooting.
Jones has repeatedly claimed the tragedy, which left 20 children and six school employees dead, was a hoax and that the families involved were actors.
A lawyer for the families told NBC: "Jones's actions subjected the families and survivors of the Sandy Hook shooting to physical confrontations and harassment, death threats and personal attacks on social media."
Jones is a vocal gun rights activist and the host of "InfoWars," which regularly presents conspiracy theories.
He was sued by the parents of two other children killed in the shooting last month.
