Citizens for Responsible Ethics in Washington, DC filed a  FOIA request for the FBI transcripts of their "interview" with the Vice President. CREW is a private organization doing the job of Congress, collecting evidence of VP crimes:

"[R]equesting copies of the interview that the FBI conducted of Vice
President Richard B. Cheney as part of the investigation into the leak
of Valerie Plame Wilson's covert CIA identity. CREW is requesting the
same records that the House Committee on Government Oversight has
sought through a subpoena and over which the White House has claimed
executive privilege."

AG Mukasey previously refused to respond to a subpoena for similar documents citing executive privilege, prompting Georgetown LawProf Jonathan Turley to (again) suggest Congress (possibly) use inherent contempt to arrest the Attorney General. Waxman prepared a contempt resolution against Mukasey.

Two years after the 2006 "mandate," Congress is still looking for the light switch:

Turley, Nov 2006, responding to questions about enhanced Congressional oversight: "Well, first, someone has to find where the boxes are to turn lights back on in Congress."

CREW Works, Congress Diddles

Without a table for impeachment investigation, CREW has plenty of space to stomp.   Pelosi has time to attend Netroots, but "no time" to lead an impeachment investigation on torture. Yet Turley after the November 2006 election, anticipated the opposite:

Turley: "You know, one of the reasons we have a government of checks and
balances is not just for this type of partisan bickering, but it’s just
that government works better when there’s more than one set of eyes on
a problem."

Pelosi, with a gleam in her eye relishes the thought of letting the President flounder without challenge. Some observers believe the floundering would increase if there was a serious investigation.

Consider the Federalist Papers on the value of investigations and impeachment: The United States government structure should, in theory, responsibly ensure safety through impeachment:

Federalist 77: "We have now completed a survey of the structure and powers of the executive department, which, I have endeavored to show, combines, as far as republican principles will admit, all the requisites to energy. The remaining inquiry is: Does it also combine the requisites to safety, in a republican sense -- a due dependence on the people, a due responsibility?

The answer to this question has been anticipated in the investigation of its other characteristics, and is satisfactorily deducible from these circumstances; from the election of the President once in four years by persons immediately chosen by the people for that purpose; and from his being at all times liable to impeachment, trial, dismission from office, incapacity to serve in any other, and to forfeiture of life and estate by subsequent prosecution in the common course of law."

Speaker Pelosi has fallen well short of her legal duties and responsibilities, as the Framers intended. Pelosi impermissibly removed impeachment, which the Framers intended to be "at all times" a credible check on the Executive. Had she been committed to obligations as Speaker, there might not be calls to declare the Speaker's position vacant.
 
Conyers in his book expressly mentioned the Presient's crimes of "torture," but we have no official Judiciary Committee-led war crimes investigation.  Conyers promised
a "non basement" impeachment.   We're out of the basement, but still
without an investigation, just a wishy-washy hearing into the "Imperial
Presidency".

What's worse, having a mock investigation in the basement; or leaving
the Constitution in the basement during phony hearings in the Committee?

Let's turn back the clock to when Conyers was in the basement and consider what we should have asked him:

Why do we need a federal government or a democratic "victory" when a
private organization required to collect evidence and do the job of
Congress?

What happened to Checks and balances; what about the light switch called "The Constitution"?

Do you plan to investigate the President when you become Chairman; or are you going to make excuses to pretend that your hands are still tied?

Is there any collusion with the Speaker and President to thwart full invstigations?
