SACRAMENTO, Calif. (AP) – A California legislative panel has advanced pieces of a compromise state budget, but agreement remained elusive Friday on key sticking points including how to spend more than $1 billion in new tobacco tax revenue. A budget conference committee voted Thursday to boost spending on social services and expand a tax credit for the working poor. The panel also approved money for 1,500 new University of California students while placing restrictions on the UC Office of the President following a scathing audit. Democratic leaders and Gov. Jerry Brown face a June 15 deadline to work out their differences and have the full Assembly and Senate approve the budget. After that date, lawmakers will lose their pay until a budget is approved.
