Has the US Attorney investigation moved to another phase?

I'm beginning to get that strange "iceburg" feeling that something bigger is going on than what I see.

The House Judiciary Committee issued subpoenas for all documents, unredacted, related to the US Attorney firings. (Interesting details on the subpoena at FDL.)

Next, we've got the Senate Judiciary Committee requesting everything related to the Wisconsin US Attorney's prosecution of what now seems a very shaky case against a Dem right before the 2006 election.

Third, (sometimes it's the things you don't hear) has anyone noticed that the effort to get Rove and Miers under subpoena has gone quiet?

It's funny, the battle for Rove and Miers to testify stopped right about the time that "a Senior Department of Justice official" started cooperating with Schumer. Remember Monica Goodling's first 5th Amendment letter on Mar. 26th?

Fourth, it has come to our attention that a senior Department of Justice official has privately told Senator Schumer that he (the official) was not entirely candid in his report to the committee, and that the official allegedly claimed that others, including our client, did not inform him of certain pertinent facts.

That unnamed official was later revealed to be Paul McNulty.

I may be very wrong, but I can't shake this strange feeling the Dems are no longer just on a fishing expedition, but are instead looking for specific information. And if McNulty is cooperating in some way, he may be telling them where to look.

Treat this as pure speculation.
