more on the "Clinton did it too" "defense"

Waxman agrees to investigate Clinton White House.

As part of the House Oversight and Government Reform Committee’s investigation into the Bush White House’s potentially illegal partisan briefings at various government agencies, Chairman Henry Waxman (D-CA) has agreed to a request by Rep. Tom Davis (R-VA) to determine whether Clinton did it too. The Clinton White House was thoroughly investigated both during and after its term. Waxman said he believes most of the documents Davis is seeking are already in the committee’s archives:

“You have asked that the committee make a number of document requests of the National Archives for records of the Clinton administration,” Waxman wrote. “The Clinton administration was subject to vastly more scrutiny by this committee than the Bush administration has been, and many of the records you seek may already be in the committee archives.

“However,” Waxman continued, “I do agree that the committee would benefit from requesting copies of any political briefings that the Office of Political Affairs in the Clinton administration may have given to federal agencies.” […]

Waxman added that the committee’s “own archives of Clinton-era documents are so broad and voluminous that they should already contain” other documents Davis wanted, if they exist.

Is there actually a point to this, other than to waste time and money re-hashing an investigation that already took place?
