The AP reports:
The fate of $600-$1,200 rebate checks for more than 100 million Americans is in limbo after Senate Republicans blocked a bid by Democrats to add $44 billion in help for the elderly, disabled veterans, the unemployed and businesses to the House-passed economic aid package. [...]
The tally was 58-41 to end debate on the Senate measure, just short of the 60 votes Democrats would have needed to scale procedural hurdles and move the bill to a final vote. In a suspenseful showdown vote that capped days of partisan infighting and procedural jockeying, eight Republicans – four of them up for re-election this year – joined Democrats to back the plan, bucking GOP leaders and President Bush, who objected to the costly add-ons.
