Chalabi, Iran Spy or?

From Josh Marshall:

There are a handful of articles out yesterday or today in which various partisans of Ahmed Chalabi claim that top level government officials say that the spying charges against Ahmed Chalabi are not to be taken seriously --- they're merely the product of bureaucratic infighting within the US government, payback from his enemies at State and CIA.

I have sources too. And I hear quite the opposite. From what I'm told, what really cooked Chalabi's goose was that the evidence against him was sufficiently damning that his one-time advocates and protectors inside the government -- folks very high up the ladder -- simply washed their hands of him, wouldn't try to defend him.
