Using up what might have been Washington's full supply of sarcasm for the day, Rep. Anthony Weiner (D-N.Y.) on Friday offered a brutal mock defense of a Republican amendment to defund the healthcare law.

Rep. Steve King (R-Iowa) had proposed language that would defund the law and strip funding made available in prior laws, not just in the spending bill under consideration today. Rep. Rosa DeLauro (D-Conn.) raised a point of order against it, arguing that the amendment attempted to legislate on an appropriations bill, and thus should not be considered under Republican rules.

But Weiner supported King, and said it could not possibly be legislating on an appropriations bill.

"I've watched those guys, they're incapable," he said. "There's no way this is legislating. So I believe the point of order should be struck down. It's impossible … after eight weeks they haven't legislated, they had eight years in the majority they didn't legislate. How can it possibly be that the point of order is correct? 

"If you think they're legislating — impossible," he concluded. "Almost metaphysically impossible. He doesn't know how!"

The acting chairman of the House, Rep. Rob Bishop (R-Utah), then deadpanned: "The Chair is prepared to rule, and has been entertained, on the point or order." He said the point of order is sustained, and the amendment was dropped.
