Arizona GOP to hold state convention Saturday
Arizona's Republican Party will hold its annual state convention this weekend. Party leaders will gather Saturday at Grand Canyon University. They'll select the delegates who will ultimately cast their vote for the Republican nominee for President at the National Convention later this year in Tampa. Governor Brewer will attend the meeting. So will the son of presumptive Republican nominee Mitt Romney.
