WASHINGTON—U.S. Senate Republicans on Tuesday balked at Democratic efforts to push an economic stimulus measure through the chamber by the end of the week, making it likely that the Senate will wait at least until the week of Feb. 22 to vote on the roughly $80 billion package.

"It's a cake that isn't quite baked yet," said Senate Minority Whip Jon Kyl (R., Ariz.), following a Senate nominations vote.

"Not enough of our members have had an opportunity to review it, for a consensus that would permit us to move forward on it that quickly," he added.

Senate Majority Leader Harry Reid (D., Nev.), had announced earlier Tuesday that despite another snowstorm rolling through the Washington region, he hoped to bring the jobs-creation bill for a vote by the end of the week.

Both the Senate and the House are in recess the week of Feb. 15 due to the Presidents' Day holiday.
