No offense - but that committee is known for it's political attacks on both sides, and can not be considered "proof" of any kind.
As a matter of fact - here is the other side of this same committee:
Committee on Oversight and Government Reform - Republicans: Report :: Republicans respond to distorted draft Democratic CEQ report

Hey Venrooy,
I also found this:
http://www.luntzspeak.com/graphics/LuntzResearch.Memo.pdf
I think this sums it up pretty well also. Check it out and let me know what you think. It's by Frank Luntz who has done extensive work and advisement to the Republicans.
This is a pretty interesting source to be seeing the same stuff claimed by the Oversight Committee in.
