Citizens for Responsibility and Ethics in Washington (from WaPo):
A Washington ethics watchdog says it is time for Congress to crack down on lawmakers who sleep in their offices rather than pay for a place to live. Reacting to a surge in lawmakers’ bunking down in their work spaces, Citizens for Responsibility and Ethics in Washington wants the Office of Congressional Ethics to investigate whether the politicians are getting an unfair tax break and violating their own rules by making personal use of public resources.
This may be a new high — or low. If I’m following this correctly, the ethical violation is that they neither are spending the public’s money, nor their own, and sleeping on the office sofas outside working hours.
