(CNN) - Bill Clinton became visibly combative with a reporter Wednesday after being questioned about a lawsuit in Nevada that is seeking to ban caucus meetings in nine casinos on the Las Vegas strip.
The lawsuit, filed by the state teacher's union - an organization that has backed Hillary Clinton's White House bid - came Friday, shortly after Barack Obama was officially endorsed by the Culinary Union. Culinary Union members primarily work in casinos, and could constitute the majority of participants at caucuses held at those locations.
The teacher's union is claiming the at-large caucus sites would unfairly have more weight in terms of delegate allotment than caucuses throughout the rest of the state. The lawsuit also takes issue with caucuses being held midday at those sites – which could make it easier for culinary workers to caucus than it will be for other Nevadans.
Critics of the lawsuit say it is a clear attempt to suppress Obama’s support, a notion with which the former president sharply disagreed.
"Do you really believe that all the Democrats understood that they had agreed to give everybody who voted in a casino a vote worth five times as much as people who voted in their own precinct? Did you know that?" the former president said, growing visibly upset. (Watch Clinton's back and forth with the reporter)
"What happened is nobody understood what had happened. Now everybody's saying, 'Oh, they don't want us to vote.' What they really tried to do was to set up a deal where their votes counted five times, maybe even more."
Clinton also maintained that his wife’s campaign had "nothing to do" with the lawsuit," and claimed the reporter was taking an "accusatory tone."
"Get on your television station and say, 'I don't care about the home mortgage crisis, all I care about is making sure that some voters have it easier than others should count five times, and when they do vote, when its already easier for them, their vote should count five times as much as others," Clinton said in a raised voice.
"If you want to take that your position, get on the television and take it," he added, as aides pulled him away. "Don't be accusatory with me, I had nothing to do with this lawsuit."
UPDATE: A federal judge has ruled that the Democratic Party can go ahead with the 9 at-large caucuses on the strip. The ruling could have a decisive effect on the result in the state given that recent polls show a dead heat between Clinton, Obama, and John Edwards.
