Depends on what your definition of leak is

The CIA has fired an officer for leaking information to the press about U.S. secret prisons in Eastern Europe. The reporter recently won a Pulitzer Prize for the stories.

So to recap, a CIA officer that leaks information is shown the door. President Bush authorizes leaks of information about a CIA officer and shows others in his administration the door for getting caught doing it for him.
