TPM Reader JM gets it ...

There's a weak excuse emerging from Republicans for Foleygate - they might have known about the e-mails to Rep. Alexander's page, but they never knew about the explicit IMs. Too much of the media coverage right now is centering on that question, as if knowledge of the IMs is the only way to show the leadership was remiss.

But that's irrelevant, and here's why: Once ABC got hold of the e-mails, it took them one day to flush out the IMs. That's what an actual investigation looks like. The Republican leadership simply didn't want to know how bad the Foley situation was. That's just as morally negligent as if they had started digging and found the IMs.

Exactly. Hastert's et al.'s defense here seems to be that their hands were firmly clasped over their ears. They never knew.
