Arizona Gov. Doug Ducey (R) signed a bill Friday authorizing the state to participate in a federal health insurance program designed to provide subsidized health care to children from low-income families, Reuters reports. The 2010 program, already offered in the other 49 states, is geared toward kids whose families earn too much to qualify for Medicaid, but too little to purchase private insurance.

The bill was controversial in the state legislature, with many conservative lawmakers opposing the program.

"Some of us here on the floor have obviously forgotten that we were not elected to expand government programs," said state Sen. Nancy Barto (R-Phoenix). "We were elected to get rid of them."

The program, known as KidsCare, is expected to serve about 30,000 kids in Arizona. It may go into effect as early as August.
