Sanders won't respond to Obama's jab

Sen. Bernard Sanders (I-Vt.) on Wednesday declined a request to comment on President Obama's "sanctimonious" remark on Tuesday.

But the liberal senator repeated his displeasure with the tax-cut deal brokered between Obama and congressional Republicans.

"I'm not into getting in a fight with the president," Sanders told reporters. "I think the agreement that we now have is a bad agreement. I think we can do much better, and I intend to do everything I can to make it better."

Obama lashed out at far-left Democrats in comments Tuesday, labeling his critics "sanctimonious" and "unrealistic" and saying they were clinging to "purist positions." Sanders and others have been critical of Obama for giving in to GOP demands that the 2001 and 2003 tax cuts for the wealthy be extended.
