Senate Majority Leader Harry Reid (D-NV) pulled the Kerry-McCain Libya resolution, which was being debated today.
"Senator Reid vitiated cloture (ie pulled it), because Republicans said they were all going to vote against it irrespective of national security interests, solely in protest over the budget," Reid spokesman Adam Jentleson told NBC over email.
Senate Democrats had hoped to pass the Libya resolution to show a measure of support for President Obama and the ongoing operation in Libya.
Translation: It wouldn't have passed, Reid's office said. Democrats needed at least seven Republicans to advance and overcome a filibuster.
