Attorneys for the jailed independent journalist Josh Wolf have launched a new effort for his release. Wolf was sent back to prison last year after refusing a court order to hand over video of a protest in San Francisco. His lawyers have filed what’s called a grumbles motion. The motion argues Wolf’s commitment to press freedom will forever prevent him from handing over the tape. Wolf would be released if the court rules keeping him in jail would only be punitive. Wolf has spent more than 150 days in prison.
