From Fox News, April 2nd 2010:

CREW, citing a recent report pegging the lawmakers' rent at $950 per month, claims they are paying well below market rates of nearly double that for the Capitol Hill area -- though the residents deny the allegations.

Director Melanie Sloan said that such discounted lodging would count as a prohibited gift.

"It's a violation," she said.

The only exceptions would be if the lawmakers were having their expenses provided by a personal friend or if they were benefiting from "personal hospitality." Sloan said neither is the case.

"I think it's considerably below market, particularly when you add in the housekeeping services," she said, questioning the exclusivity of the location. "You have to be invited, and only members of Congress seem to be those people."

The complaint names Sens. Sam Brownback, R-Kan.; Tom Coburn, R-Okla.; Jim DeMint, R-S.C.; and John Ensign, R-Nev., as well as Reps. Mike Doyle, D-Pa.; Heath Shuler, D-N.C.; Bart Stupak, D-Mich.; and Zach Wamp, R-Tenn.
