Gov. Jan Brewer has vetoed a bill that could force able-bodied Medicaid recipients to get a job and limit some to a maximum of 5 years of insurance.

Brewer vetoed the bill by House Speaker Andy Tobin on Tuesday. A veto letter explaining her reasons hasn't been released.

House Bill 2367 requires the state's Medicaid program to apply for a waiver from federal regulators every year to allow it to impose the new rules.

Federal officials say they likely would not approve the waivers. Tobin has said he believes Medicaid's position could change.

Tobin's bill also imposed copays on unneeded ambulance and emergency room use. He said they're needed to protect the state from excess expenses. Democrats argue they would limit the effectiveness of the health system for poor Arizonans.
