I have to pay more attention. The NYT
informs me that:
At one point, Mr. Cheney's onetime press secretary, Pete Williams of NBC News, asked Mr. Fitzgerald how the prosecutor could take the word of "three reporters" (including his current bureau chief and boss, Tim Russert) "versus the vice president's chief of staff," with whom Mr. Williams served in the Pentagon when Mr. Cheney was secretary of defense in the first Bush administration.
I know I should have known this, now some of his reporting makes more sense.
