The Arizona Senate's appropriations committee has approved $60 million in extra spending to overhaul the state's child welfare agency and deal with a massive backlog of cases.

The panel unanimously approved the spending Wednesday morning despite tough questioning of new agency director Charles Flanagan about how the money will be spent by some Republican members.

The House appropriations committee is also hearing testimony on the funding. Two other committees in the Senate and House are poised to pass bills making policy changes creating a new Department of Child Safety to replace the old Child Protective Service department.

Gov. Jan Brewer proposed the overhaul after revelations late last year that more than 6,500 abuse and neglect reports weren't investigated.

The full Legislature could vote on the bills Thursday.
