Washington D.C.'s controversial "C Street House" – which lost part of its tax-exempt status last year – is the subject of a new round of complaints filed by a group of clergy and a government watchdog in the last week.

The Citizens for Responsibility and Ethics in Washington – CREW for short – cites news reports that say House members and some senators have paid below-market rents to live in a house on C Street SE that is owned by a Christian prayer group known as the Fellowship. CREW wants the House and Senate ethics committees to determine whether the monthly rent, reported to be around $950, is below the market value. If so, CREW says, the discount could amount to an illegal gift.

Earlier this week another group called Clergy VOICE asked the IRS to investigate the tax implications of accepting lodging at the C Street house.
