The lawsuit, which targets Maricopa County, will be filed on Friday, the Post reported. It calls on the district court to look at the polling location plan ahead of the general election in November and aims to put an end to state policies that it says negatively affect minorities.

The lawsuit comes after Maricopa County cut its number of polling locations by 85 percent, from 400 locations in the primary of 2008 to just 60 this year.

The cut had a large impact on the county's black, Hispanic and Native American communities. Those communities had fewer polling locations in 2016 than did white communities, while some had none at all, the lawsuit alleges.

Arizona’s “alarmingly inadequate number of voting centers resulted in severe, inexcusable burdens on voters county-wide, as well as the ultimate disenfranchisement of untold numbers of voters who were unable or unwilling to wait in intolerably long lines,” the lawsuit says.

"Arizona has a history of problems with guaranteeing the rights of their citizens to vote, and with this lawsuit we hope to stop it now in time for the 2016 general election,” said Marc E. Elias, the elections lawyer for Clinton’s campaign.

The lawsuit if being filed on behalf of the Democratic National Committee, the Democratic Senatorial Campaign Committee, the Arizona Democratic Party and some Arizonans. The Clinton campaign will join it after it is filed on Friday.

On the day of the Arizona primary, there were reports of polling places running out of ballots. Hundreds of voters in the state also remained in line even after media outlets projected Clinton would win the state.

An Arizona official then appeared to blame the voters for the long lines in the presidential primaries. When asked who was to blame, Maricopa County recorder Helen Purcell said: “The voters, for getting in line, [or] maybe us for not having as many polling places as we usually have."
