A US federal magistrate ruled Friday that prosecutors can demand Twitter account information of certain users in their criminal probe into the disclosure of classified documents on WikiLeaks.
Three of the five account holders targeted by the government had asked the judge to reverse an earlier order she issued requiring Twitter to turn over the information to prosecutors. The Twitter users argued that the government was on a fishing expedition and its request amounted to an unconstitutional violation of their freedom of speech and association.
The original order issued by Buchanan in December 2010 at prosecutors' request sought account information from Wikileaks founder Julian Assange and Pfc. Bradley Manning, who is being held at Quantico Marine Corps Base amid allegations that he leaked classified documents about the Iraq and Afghanistan wars to WikiLeaks.
Three other accounts belonging to American Jacob Appelbaum, Dutch citizen Rop Gonggrijp and Birgitta Jonsdottir, a member of Iceland's parliament, were also targeted. Those three challenged the court order. Assange has contended that, as an Australian citizen, he is not subject to American law.
Buchanan also rejected a request that would have required the government to disclose whether it sought similar records from other social networking sites like Facebook.
