The government watchdog group Citizens for Responsibility and Ethics in Washington says Rep. Jason Chaffetz and other lawmakers who sleep during the week in their offices should be investigated for misusing official resources.

As recently as a few years ago, the practice of members sleeping in their offices was an open secret, although rarely discussed outside of Capitol Hill. But the most recent congressional election brought a wave of new members who decided to forego paying Washington D.C.'s rent prices, and weren't shy about discussing it with the media.

CREW cites Superintendent of House office buildings, Bill Weidemeyer, as saying that members sleeping in their offices adds "some burden to the housekeeping staff," and that the swath of overnight guests in House offices has hindered building maintenance, since members complain about the noise of late-night construction.
