This is bizarre
I think this one is going to backfire and look like sour grapes but the Washington Post is reporting that the Democratic National Committee is suing the Russian government, the Trump campaign and WikiLeaks. They allege a conspiracy to disrupt the 2016 campaign.
"The complaint, filed in federal district court in Manhattan, alleges that top Trump campaign officials conspired with the Russian government and its military spy agency to hurt Democratic presidential nominee Hillary Clinton and help Trump by hacking the computer networks of the Democratic Party and disseminating stolen material found there," according to the Washington Post.
Even under US law, where everyone sues everyone for anything, sovereign nations have immunity from lawsuits.
