That's why this whole GOP 'we've gotta know the identity of the whistleblower' defense is so asinine.The whistleblower obviously knew what was going on because his or her claim is accurate.
It *might* be pertinent if the anonymous whistleblower had fabricated it all for partisan purposes and we need to have that person answer for it. But everything the whistleblower said WAS TRUE and incriminating testimony and documented evidence has come out since the report was filed.
