From the transcript:

Let me give you another example of what‘s being passed off as politics right now by lobbying interests on the political right.

When the climate change bill came before the House last month, the Democratic congressman named Tom Perriello of Virginia received a letter purportedly from a nonprofit Hispanic group in his district, and the letter urged him to oppose the cap-and-trade legislation. He received similar letters from what were purportedly his local branches of the NAACP. Only, these letters weren‘t actually from that Hispanic group in his district or the NAACP. A Republican lobbying firm in Washington has admitted to impersonating those local nonprofits and sending Congressman Perriello fake letters to get him to oppose the climate change legislation.

Congress is now investigating this incident.
