contempt for not cooperating with a court and be sentenced to jail. Nothing new. The newspaper doesn't want to potentially face penalties but they weren't previously immune from such action either. The Plame case has changed nothing in that regard.
Here's one example from 2001:
Freelance writer and book author Vanessa Leggett was released from federal custody in Houston on Jan. 4, after serving 168 days in jail for refusing to testify before a federal grand jury and turn over her research materials. A panel of the U.S. Court of Appeals sitting in Houston (5th Cir.) upheld the July 20 contempt order on August 17, finding journalists do not have a right to refuse to testify before a grand jury.

Television reporter released early from home confinement
Two months before his sentence was set to end, television reporter Jim Taricani won freedom from home confinement for refusing to identify a confidential source.
April 12, 2005 -- The court battle between federal prosecutors and a television reporter Jim Taricani is over after U.S. District Judge Ernest C. Torres granted a request last week to cut short his six-month home confinement sentence by two months.
Taricani is expected to return to work Wednesday at WJAR television in Providence, R.I. Torres signed an order for early release Wednesday, but the order did not take effect until Saturday. Taricani had been confined to his home since Dec. 9 when Torres sentenced him for criminal contempt-of-court for refusing to reveal the confidential source of a videotape showing a Providence official taking a bribe from an FBI informant.
In a one-page order, Torres noted that "the supervising probation officer reports that Mr. Taricani has fully complied with all conditions and the probation officer recommends that his petition be granted," The Providence Journal reported. The order also said that special prosecutor Mark DeSisto did not object to Taricani's early release, the paper reported.
