Arizona is latest state to add abortion measure to November ballot

Arizona voters will get to decide in November whether to add the right to an abortion to the state constitution.

The Arizona secretary of state's office said Monday it had certified 577,971 signatures - far above the required number that the coalition supporting the ballot measure had to submit in order to put the question before voters.

The coalition, Arizona for Abortion Access, said it's the most signatures validated for a citizens initiative in state history.
