Ah, so since Sestak has admitted it and the WH denies it, I say we've most definitely reached the IC point. I go back to the hue and cry made that an IC was necessary to investigate Newt Gingrich where no crime was charged nor found, just the pit yorkie Bonoir yapping. Surely we've passed that standard now.
Not that I've noticed, but is Bonior even in Congress any more? If not, guess he served his purpose, eh?
And you're right, now that there's the appearance of impropriety and knowing what happened with the Illinois Senate seat, we really need someone independent to get in and investigate the WH.
It is also my opinion that a fully-qualified exorcist will be needed to make the place safe for occupancy by humans whenever the current crop is forced to leave (I don't expect them to leave willingly no matter the reason given).
