Four years after former Gov. Jan Brewer pushed a Medicaid expansion plan through the Legislature, the plan will be challenged in court.

On Feb. 14, the Arizona Court of Appeals will weigh the legality of a the state insuring more than 400,000 low-income residents.

This comes as Republicans who now control Congress begin their promised repeal of President Barack Obama's health-care-overhaul law that allowed the expansion.

The hearing was announced as advocates for the expansion continue a series of news conferences across the state designed to show just how it and other parts of Obama's law have helped Arizonans.
