Story highlights The DNC chair said the suit aims to counter "voter disenfranchisement"

Democratic lawmakers have claimed there were some primarily Latino neighborhoods that had no polling places

Washington (CNN) The Democratic National Committee, along with Hillary Clinton and Bernie Sanders' campaigns, are suing the state of Arizona following complaints of voter suppression during the Arizona primary last month.

Voters endured long waits to use one of Maricopa County's 60 polling stations last month. There were at least 200 polling stations in 2012, but Republican officials said they decreased the number to save money.

Even after waiting in line for hours, some people were not allowed to vote. At least 20 Democratic voters contacted the Arizona Democratic Party to say that when they arrived at the polls, they were told that they were registered as Independents and therefore unable to vote in the closed primary.

DNC Chairwoman Debbie Wasserman Schultz said Thursday that the lawsuit is "to reverse Arizona's culture of voter disenfranchisement prior to the 2016 election."

"As Democrats, we believe the right to vote is our most fundamental right -- the right that defends all of our other rights. Democrats also know that when we see injustice, we must act," Wasserman Schultz said in a statement.
