Washington (CNN) -- Republican leaders will propose cutting more spending to balance the amount of additional disaster relief money in a short-term government spending measure defeated earlier by the House, two Republican sources told CNN on Thursday. The additional spending cut, called an offset, would be roughly $100 million from a Department of Energy loan program linked to the solar panel firm Solyndra, which recently collapsed, said the sources -- a GOP aide and a Republican member of Congress -- who spoke on condition of not being identified. The plan, which faces sharp Democratic opposition, could pave the way for a partial government shutdown when the current fiscal year ends on September 30 if it is not resolved.

The move was intended to persuade the 48 Republicans who voted against the GOP measure Wednesday night to change their minds, according to the @placeholder aide.
The House vote Wednesday was 195 "yea" and 230 "nay," with 48 Republicans joining all but a handful of minority @placeholder in opposing the short-term spending plan.
