Purge

Monica Goodling, you will remember, resigned from her position at Justice and took the fifth before she was called to take the stand (a first?) by the congressional committee investigating the attorney purge. Then she was offered immunity by the committee in exchange for her testimony.

But now, the DoJ is investigating her. (I love it when agencies are permitted to police their own.)

[T]his raises a weird possibility: the fact that the DOJ is investigating Goodling could put a roadblock in the way of the investigating committees' efforts to give her immunity and force her to testify on Capitol Hill. So Goodling's new alleged wrongdoing could have the perverse effect of preventing her from being forced to go up to Capitol Hill and reveal what she knows about what happened in the Purge.

And wouldn't that be the whole point of the DoJ's investigation?

....but hey, do what you want....you will anyway.
