"Infowars is the tip of a giant iceberg of hate and lies that uses sites like Facebook and YouTube to tear our nation apart. These companies must do more than take down one website. The survival of our democracy depends on it," Murphy tweeted Monday.

Apple, Facebook, YouTube, Pinterest, and Spotify removed Alex Jones and his InfoWars show from their platforms in recent days, citing violations of their codes of conduct relating to hate speech.

Apple deleted all episodes for five of InfoWars' six podcasts, including the popular "Alex Jones Show" podcast, which was hosted by Jones, a prominent conspiracy theorist.

Facebook made a similar move by taking down four InfoWars pages after originally removing only certain videos it said violated its hate speech and bullying policies. Jones was previously suspended from the social media platform for 30 days.

YouTube also removed Jones' channel from the platform.
