Washington (CNN) - The Senate adjourned Friday without approving extensions of cash and health insurance benefits for the unemployed after a lone senator blocked swift passage due to his insistence that Congress first pay for the $10 billion package.
Retiring Sen. Jim Bunning, R-Kentucky, led a spirited Senate debate with Democrats over the issue - at one time cursing at another senator on the floor. Bunning said he doesn't oppose extending the programs - he just doesn't want to add to the deficit.
According to two Democratic aides on the Senate floor Thursday night, Bunning muttered "tough s-" as Sen. Jeff Merkley, D-Oregon, criticized Bunning's stance on the package.
An aide to Merkley said the senator didn't hear the remark. A spokesman for Bunning said he was aware of the reports about the senator's language but didn't have a comment.
