WASHINGTON – Senate leaders groped for a last-minute compromise Saturday to avoid middle-class tax increases and possibly prevent deep spending cuts at the dawn of the new year as President Barack Obama warned that failure could mean a “self-inflicted wound to the economy.”

Obama chastised lawmakers in his weekly radio and Internet address for waiting until the last minute to try and avoid a “fiscal cliff,” yet said there was still time for an agreement.

“We cannot let Washington politics get in the way of America’s progress,” he said as the hurry-up negotiations unfolded.
