House Homeland Security chair calls on Facebook, YouTube, Twitter and Microsoft to explain the spread of mosque shooting video

House Homeland Security Chairman Bennie Thompson wrote to the CEOs of Facebook, YouTube, Twitter and Microsoft requesting a briefing next week on the spread of violent content on their platforms.

Thompson's request follows Friday's mosque shootings in New Zealand, where a suspected shooter livestreamed a video of one of the attacks, which was later shared repeatedly on tech platforms.

Thompson said tech companies must display the same transparency around how they handle all forms of violent extremism, not just that of ISIS and Al-Qaeda.
