Arizona officials are weighing in on the long wait times many Maricopa County voters experienced during the state's presidential primary.

Phoenix Mayor Greg Stanton wants the U.S. Department of Justice to investigate whether county elections officials illegally put fewer presidential primary polling locations in poor or minority-heavy areas for Tuesday's voting.

Sites across the county were jammed and lines topped five hours at some spots.

Voters today gathered outside the Maricopa County Recorder’s office, protesting long lines during the state’s presidential preference election yesterday. As Arizona Public Radio’s Aaron Granillo reports, thousands of voters waited for hours to cast their ballots.

 Donald Trump and Hillary Clinton prevailed in Arizona's primary, putting them a step closer to wrapping things up and getting on with a head-to-head race for the White House, unobstructed by rivals who just won't quit.

Contests Tuesday in Arizona, Utah and Idaho were deciding how near that moment might be for one of them or both. The two are clear front-runners, but Clinton has an easier path. Democratic rival Bernie Sanders won in Utah and Idaho but Clinton's win in Arizona prevented the Vermont senator from cutting deeply into her delegate lead by night's end.

Arizona officials are getting tired of footing the $6 million bill for the state's presidential primary and want to foist the cost onto the political parties as states around the country weigh the cost of the contests.

Colorado may go the other direction, bringing back state-run primaries. Utah lawmakers voted to scrap primaries in favor of caucuses in the two most recent presidential election cycles. States have come up with various ways to handle the contests every four years, and cost is a factor.

Bernie Sanders is continuing his presidential campaign swing through Arizona with a stop in Flagstaff.

The Vermont senator, who is coming off a wave of primary losses to Hillary Clinton, is scheduled to hold a town hall meeting Thursday evening in the state's high country at the Twin Arrows Navajo Casino Resort.

His appearance comes two days after Sanders held a rally in Phoenix.

The Democratic candidate did not mention his defeats to Clinton in other states.

A bill overhauling the state's campaign finance laws that has passed a House panel would also allow politicians to divert campaign contributions to other politicians.

Democratic Rep. Ken Clark says the measure would amount to a fundamental change in state politics that allows politicians to buy votes from colleagues using campaign contributions. Clark calls it the "king maker provision."

Bill sponsor Sen. Adam Driggs added the provision onto a sweeping bill he said is designed to simplify and re-organize the state's campaign finance code.

Bernie Sanders is avoiding mention of his losses as he kicks off his Arizona presidential campaign.

The Vermont senator spoke for an hour Tuesday night at the Phoenix convention center. He did not mention his defeats by Hillary Clinton earlier in the day in primaries in Florida, North Carolina and Ohio.

Instead he reminded Arizonans that they are the next major state to vote in the Democratic contest for president. He urged the crowd to come out to vote in a week, March 22.

Arizona's Republican primary also is that day.


UPDATE: According to the U.S. State Department, former State Senator Jack Jackson, Jr. is not running for state senate in Legislative District 7.

So far, only one candidate has officially announced her senate run for the state’s largest legislative district, LD-7. Arizona Public Radio’s Ryan Heinsius reports.
