In a very unusual move, WikiLeaks has been subpoenaed via Twitter. In a tweet on Friday, a law firm representing the Democratic National Convention in its civil lawsuit against WikiLeaks and other defendants served legal documents formally notifying the non-profit that it is being sued. The lawsuitalso names a long list of other people and organizations, including the Russian government and Donald Trump’s presidential campaign, that the DNC claims worked together to sway the 2016 election in Trump’s favor.

The Twitter account has no other tweets and appears to have been set up this month by Cohen Milstein, the DNC’s law firm, for the purpose of serving papers to WikiLeaks.
