It looks like on Friday, Al Gore had some fun times with Congresswoman Marsha Blackburn when she insinuated that he has monetary motivations behind his advocacy of a green economy and cap-and-trade legislation.

She then went on to ask if Gore stands to make money off of KP's investments into cleantech (or "40 companies that are going to benefit from cap-and-trade legislation").
Gore responded by saying, "Congresswoman, if you believe the reason I have been working on this issue for 30 years is because of greed, you don't know me." Here's the whole video. Worth a look:
