WASHINGTON - The top Republican in the Senate said Sunday that GOP lawmakers "may well" vote for a jobs bill this week.

Sen. Mitch McConnell, R-Ky., prefers a costlier version drafted with GOP input and he didn't commit his support to advance the legislation on Monday to a final vote this coming week.

The pending measure would provide businesses that hire the unemployed a one-year break from payroll taxes and a $1,000 tax credit if those workers stay on the job for a full year. The cost is estimated at $13 billion.
