This is usually Nicole's beat, but CREW:

CREW just asked the Senate Ethics Committee to investigate Senator Pete Domenici (R-NM) for his role in the growing scandal surrounding the dismissal of David Iglesias, the U.S. Attorney from New Mexico.

Sen. Domenici has now admitted that he called Mr. Iglesias, stating “I asked Mr. Iglesias if he could tell me what was going on in that investigation and give me an idea of what time frame we were looking at.”

In a discussion of Senate Rule 43, the Senate Ethics Manual states that “[t]he general advice of the Ethics Committee concerning pending court actions is that Senate offices should refrain from intervening in such legal actions . . . until the matter has reached a resolution in the courts.”
