The congressional caucus gunning for AG Alberto Gonzalez and, perhaps, seeking a thorough investigation, seems undeterred by last week’s failure to pass a vote of no confidence against the nation’s lead law enforcer. Subpoenas are now in the works for two White House insiders as Democrats in Congress press ahead with their investigation into the firing of eight federal prosecutors. Former White House counsel and one-time Supreme Court nominee Harriet Miers will soon be called to testify. She’ll be joined by former White House political director Sara Taylor.

It’s a direct volley into the West Wing as the Bush Administration has thus far refused to allow sworn testimony from senior White House officials. If Big Al’s testimony was any indication, however, this volley will be nothing but duds.
