Maricopa County will count outstanding provisional ballots through the weekend if necessary despite a state law that generally says all vote tallying must be completed by Friday, officials said.

U.S. Sens. John McCain and Jon Kyl led a group of Republican officials Wednesday denouncing a ballot measure that would allow medical marijuana.

Arizona Gov. Jan Brewer said Oct. 20 that she opposes a November ballot measure that would legalize medical marijuana in the state, arguing that it would cause pot to "needlessly and harmfully proliferate."
