Well, it appears that Nora R. Dannehy, the US Attorney assigned to investigate the politically motivated firings of US Attorneys, has been aggressively pursuing the case, “meeting with defense lawyers, dispatching subpoenas and seeking information about the events.”
What’s more, one of her investigators has formally contacted Alberto “Abu” Gonzalez, which means that any lies or omissions to that investigator are handled under obstruction of justice, which is much easier to prove than perjury.
