PHOENIX - The complaint, filed in Federal court, accuses the Donald Trump campaign and the Arizona Republican Party of conspiring to threaten, intimidate and prevent minority voters in urban neighborhoods from voting in the 2016 election.
The goal: depress voter turnout so the GOP can win.
The complaint asks a judge to order Republican poll watchers not to question voters leaving polling places or harass voters in any way.
An attorney representing the Arizona Republican Party says the complaint is nonsense.
"I don't think it will go anywhere. The relief they request is extreme to tell people not to do things in the future that are First Amendment protected," said Tim La Sota.
At the state Democratic Party headquarters in Phoenix, we asked a spokesperson for his response to what the Republicans had to say and he declined, saying the lawsuit speaks for itself.
Meanwhile, Maricopa County Recorder Helen Purcell says she is confident elections are conducted fairly in Arizona and contrary to what Trump says at his rallies, there is no rigging going on.
"It is not. Don't care what he said, the election is not rigged, we take seriously what we do," said Purcell.
This complaint is another indication of the tense atmosphere in the run-up to the election on November 8th.
