That's incorrect. No reporters have actually been indicted. Rosen is essentially an "unindicted co-conspirator" under the law.
Risen (not Rosen) was subpoenaed to testify in a whistleblower prosecution case. He is refusing at this point. If the Court orders him to testify, he says he will not. At that point, the Court can hold him in contempt and jail him.
Thank you for the corrections.
