A Virginia district court judge has ruled the U.S. government can collect the private information of three WikiLeaks volunteers from the social networking site Twitter. The government has subpoenaed all the account information of Icelandic lawmaker Birgitta Jónsdóttir, Dutch activist Rop Gongrjip and programmer Jacob Appelbaum. Thursday’s ruling upholds a lower court judgment in March that found the subpoena does not violate constitutional protections against unreasonable searches.
