Over 20 people and millions of $

For the Copenhagen summit. They won't say where they stayed or how much they spent until they have to. Many of them flew over commercial, but over 20 went all expenses paid. CBS has the story:

But finding out more was a bit like trying to get the keys to Ft. Knox. Many referred us to Speaker Pelosi who wouldn't agree to an interview. Her office said it "will comply with disclosure requirements" but wouldn't give us cost estimates or even tell us where they all stayed.

Senator Inhofe (R-OK) is one of the few who provided us any detail. He attended the summit on his own for just a few hours, to give an "opposing view."

"They're going because it's the biggest party of the year," Sen. Inhofe said. "The worst thing that happened there is they ran out of caviar."
