Prosecutors investigating the disclosure of thousands of classified government documents by the anti-secrecy group WikiLeaks have gone to court to demand the Twitter account activity of several people linked to the organization, including its founder, Julian Assange, according to the group and a copy of a subpoena made public late Friday.The subpoena is the first public evidence of a criminal investigation, announced last month by Attorney General Eric H.
