Why does Eric Holder still have a job?

As Ryan Lizza just said on CNN, the Obama Administration “crossed a line that had never before been crossed” — not even by Richard Nixon — in identifying Fox News reporter James Rosen as a criminal co-conspirator during its investigation of leaks.

Journalists should not be prosecuted for doing their job, Obama said this week, yet his attorney general did just that.

 “I have raised these issues with the attorney general, who shares my concern. So he has agreed to review existing Department of Justice guidelines governing investigations that involve reporters, and will convene a group of media organizations to hear their concerns as part of that review. And I have directed the attorney general to report back to me by July 12th.”

Imagine Nixon asking John Ehrlichman to review Watergate.

I doubt Holder will suggest he be fired. But Obama loses credibility each day his attorney general remains in office. The public may not care, but the media shouldn’t stop hammering away at the administration until Holder is fired or, in Washington parlance, resigns to spend more time with his family.
