Cracks have started to appear in the wholehearted Democratic support for embattled Attorney General Eric Holder as he faces possible contempt hearings for refusing to hand over papers relating to the Fast and Furious gunrunning scandal.

Three House Democrats and one Senate candidate have added their voices to the growing clamor for Holder and his Justice Department to come clean on the scheme that allowed thousands of guns to fall into the hands of violent Mexican drug cartels.

The move comes the day beforecongressmen will be given the opportunity to vent on their feelings in the case in a “special order” session which is expected to result in a concerted Republican call for Holder to quit or be fired.
