January 8 2021 Jack Dorsey Chief Executive Officer Twitter Inc 1355 Market Street Suite 900 San Francisco CA 94103 Dear Mr Dorsey In case you have not already done so I request that Twitter work to immediately preserve any and all posts communications videos and other media meta-data cloud backups and subscriber information whether currently on your platform or in any backup or archived state that may be associated with Wednesday’s insurrectionist attack on the United States Capitol I encourage you to undertake reasonable measures to identify this content in order to preserve it in connection with or anticipation of formal legal process requests you may receive Along with the rest of the world I know you watched with horror as an angry mob incited by the President and prominent Republican officials and media personalities ransacked the Capitol and threatened the safety and lives of those within it These lawless acts resulted in a number of deaths including the tragic death of a Capitol Police officer This mob was organized coordinated and in many cases broadcast via your communications services and products Efforts to bring the perpetrators to justice will inevitably involve digital evidence associated with those products and services While the rioters attacked and roamed the halls of the Capitol hundreds of them took the time and the opportunity to record or take pictures of the events later posting them to their social media accounts or sharing them via text or mobile messaging platforms to celebrate their disdain for our democratic process Others livestreamed their traitorous acts broadcasting their crimes to the world in realtime The United States Capitol is now a crime scene The FBI and other law enforcement agencies are currently investigating the events of that day and trying to piece together what happened and the perpetrators involved The prospect of litigation on behalf of the victims of the mayhem also is highly likely The texts videos and pictures posted to your platform – and associated meta-data cloud backups and subscriber information – are critical evidence in helping to bring these rioters to justice I appreciate your prompt attention to this important matter Sincerely Mark R Warner
