Arizona House Speaker Andy Tobin says he plans to call a vote on a state budget proposal despite opposition from a group of fellow Republicans who want more child welfare and education spending.

Tobin said Thursday morning that he planned to push the package when the House convened at 11 a.m. But the session was delayed until early afternoon for unknown reasons.

Tobin dismissed concerns that the six opposition Republicans can block the plan.

The six have been negotiating with House leaders since blocking approval of the $9.2 billion Senate-approved plan on Monday. They said Wednesday they had rejected changes presented by Tobin and other leaders as too little to deal with public education and the crisis in the state's child welfare system.
