Oklahoma Gov. Mary Fallin has signed a state measure to ban cities and towns in Oklahoma from raising the minimum wage.

"Mandating a minimum wage increase at the local level would drive businesses to other communities and states, and would raise prices for consumers," she said in a statement.

Organizers of a petition drive in Oklahoma City to raise the minimum wage said the state statute is a direct assault on their effort. Organizers are mulling court action against the measure as unconstitutional and also a statewide petition drive to rescind the new law.
