WikiLeaks founder Julian Assange says Manning case shows news groups must advocate for leakers

WikiLeaks founder Julian Assange says the conviction of U.S. Army Pvt. Bradley Manning shows that journalists now must to fight shoulder-to-shoulder to keep their sources safe.

In an interview in London immediately following Manning's conviction on espionage charges Tuesday, Assange said media organizations should follow WikiLeaks' lead by advocating on leakers' behalf.

U.S. journalistic organizations typically steer clear of advocacy on their sources' behalf, but Assange said it was time for that to change.

He said it was "an obligation on all journalists to protect their sources — technically if possible — and provide some legal and political support."

Assange was speaking from the Ecuadorean Embassy in London, where he has been holed up for more than a year to escape extradition to Sweden on sex crimes allegations.
