Earlier this month, the FBI served a subpoena on David House, one of the founders of the Bradley Manning Support Network who helped publicize the oppressive conditions of Manning’s solitary confinement at the Quantico Marine Corps Base. U.S. Army Private Manning has been imprisoned without charges for his alleged role in releasing classified U.S. documents to the online whistleblowing website, WikiLeaks. House testified before a grand jury last week investigating WikiLeaks and invoked his Fifth Amendment right against self-incrimination. Political and legal blogger Glenn Greenwald of Salon.com says if House and other witnesses are offered immunity, they will no longer be able to invoke this right and may refuse to cooperate with the grand jury, risking jail time rather than aid the investigation.
