The Congressional committee investigating the January 6 Capitol riots has subpoenaed internet giants Twitter, Facebook, Reddit and Alphabet to access information relevant to the 2021 events, amid what it called ‘inadequate responses’ from them.

The panel chairman expressed that key questions for the panel included how the ‘spread of misinformation and violent extremism contributed to the violent attack’, as well as what steps were taken by the social media giants to prevent radicalization.
