Congressional Democrats may water down or repeal new tax-reporting rules that are supposed to raise $16 billion for health-care legislation, facing a chorus of criticism about the rules. House Democrats were forced to postpone a vote late Thursday on a GOP motion calling for repeal of the reporting requirement. That, in turn, delayed action on an $11 billion bill that expands federally-subsidized bonds for infrastructure projects. House lawmakers may add language to the infrastructure bill to weaken or repeal the IRS reporting regime, Democratic aides said. A vote on a revised infrastructure package could come as early as Friday, but House Democratic aides said no final decisions have been made.
