On 14 December 2010, in relation to ongoing investigations of WikiLeaks, the US Department of Justice issued a subpoena ordering Twitter to release information regarding Gonggrijp's account as well as those of Julian Assange, Chelsea Manning, Birgitta Jónsdóttir, Jacob Appelbaum and all 637,000 users following @wikileaks. The reason is Gonggrijp's assistance in enabling WikiLeaks to release the "Collateral Murder" video in April 2010, a WikiLeaks action.
