Why Carol Lam was Fired

TPM Muckraker has an excellent summary on the reasons why it believe that Carol Lam, the USA for Southern California, was fired.

-- Despite the fact that it was one of the highest profile federal investigations being undertaken at the Department, Lam's investigation into Duke Cunningham and others is never mentioned in the Justice Department emails that have been released. Not once. This must have been discussed at the highest levels, but we've seen no record of those communications.
