Families of Pulse shooting victims suing social media companies

ORLANDO, Fla. (WLS) -- The families of three victims killed in the mass shooting at the Pulse nightclub in Orlando, Florida, are suing Facebook, Google and Twitter.

The families claimed the social media companies made it too easy for Isis and other terrorist organizations to spread propaganda used to attract and train new recruits.

Earlier this month, Facebook, Microsoft, Google and Twitter all said they would share a database of terror images and videos to more quickly remove terrorism content.

In June, Omar Mateen opened fire in the gay nightclub, killing 49 people and injuring 50 more.
