The congressional committee investigating the January 6, 2021 storming of the US Capitol on Thursday subpoenaed records from YouTube, Facebook, Twitter and Reddit that would detail the use of social media in the attack. The records could help explain "how the spread of misinformation and violent extremism contributed to the violent attack on our democracy," said Bennie Thompson, chairman of the House Select January 6 Committee. Thompson said the companies had not responded adequately to requests for information to help in its investigation of the violent attack a year ago on the Capitol by supporters of then-president Donald Trump.
