A state senator is pressing his bill to overhaul Pennsylvania's pension system for state and public school employees since a competing House bill is stalled.

Lancaster County Sen. Michael Brubaker said  he'll ask Senate GOP leaders to advance his bill.

Brubaker's bill would convert the traditional pension system into a 401(k)-style system. Democrats oppose it and Senate Republican leaders aren't committing to holding a vote on it.

Meanwhile, House Republican leaders are struggling to win enough votes to pass a bill that Gov. Tom Corbett backs. That bill would combine a limited pension with a 401(k)-style plan that provides a smaller benefit than employees get under the present system.

Time is running short. The fiscal year ends June 30 and Corbett insists that lawmakers pass pension legislation before they head home for the summer.
