In what appears to be the first bit of evidence that a grand jury has begun to investigate WikiLeaks, the United States has asked Twitter for information of the accounts of the group and five current and former associates. The request for information was supposed to be secret, but Twitter challenged that aspect of the subpoena in order to notify the users that their information had been requested, giving them a chance to file a legal challenge. That has led to suspicion that other Internet sites, namely Facebook and Google, may have received similar requests and quietly complied, reports the Guardian. The U.S. government has asked for details on the accounts and private messaging on Twitter accounts used by WikiLeaks founder Julian Assange, suspected leaker Bradley Manning, Icelandic Member of Parliament Brigitta Jonsdottir[!!!], Dutch hacker Rop Gonggrijp, and U.S. programmer Jacob Appelbaum, who had previously worked with the group. "If the Iranian government was to attempt to coercively obtain this information from journalists and activists of foreign nations, human rights groups around the world would speak out," Assange said in a statement. Some of the targets of the subpoenas were quick to praise Twitter. "It appears Twitter, as a matter of policy, does the right thing," Gonggrijp said. "Heaven knows how many places have received similar subpoenas and just quietly submitted all they had on me."
