An attorney for WikiLeaks founder Julian Assange says he has heard that U.S. authorities have secretly empaneled a grand jury in Virginia in an attempt to indict Assange. Attorney Mark Stephens made the claim in an interview with Al Jazeera. Assange has been held in a London jail since last Tuesday on an international warrant to face sexual crime allegations in Sweden. While international protests in support of Assange continue around the world, calls are increasing for Julian Assange to be charged in the United States. Over the weekend, President Bush’s former Attorney General Michael Mukasey said he hopes to see Assange prosecuted under the Espionage Act of 1917.
