The National Journal reports:
Republicans on the House Transportation and Infrastructure Committee are starting to quietly defend earmarks, three years after Congress banned the practice because members said it wasted taxpayer dollars during a time of trillion-dollar deficits.
As another NJ article puts it:
One of the chief complaints about the earmark ban from both Republicans and Democrats is that it takes away Congress's ability to direct taxpayer resources and leaves all that power in the hands of the administration. This is particularly troubling to Republicans, who don't trust President Obama to abide by any of their wishes. But it also worries some Democrats, who don't want Congress to unnecessarily cede authority to another branch of government.
