How Many in Congress Got All-Expense Paid Trips to Denmark on Taxpayer Dime?

(CBS News) - CBS investigative correspondent Sharyl Attkisson reports that cameras spotted House Speaker Nancy Pelosi at the summit. She called the shots on who got to go. House Majority Leader Steny Hoyer, and embattled Chairman of the Tax Committee Charles Rangel were also there. They were joined by 17 colleagues: Democrats: Waxman, Miller, Markey, Gordon, Levin, Blumenauer, DeGette, Inslee, Ryan, Butterfield, Cleaver, Giffords, and Republicans: Barton, Upton, Moore Capito, Sullivan, Blackburn and Sensenbrenner. That's not the half of it. 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."
