Did administration suppress internal EPA report challenging CO2 "endangerment"?

This could turn out to be interesting.

With the public’s belief in CO2-driven global warming cooling as fast as the earth has been for the last few years, the Left is desperate to enact their cap-and-trade tax while the “gettin is still good”.  Even Australia is backing off their cap and trade plans a bit.

So I guess it should come as no surprise, that the current administration is ignoring, and possibly tried to bury, an internal report critical of the assumption that CO2 poses a public danger, and therefore can be regulated.

Why else would they be scheduling a vote in the House for this week?  Seems someone is in a bit of a hurry…
