PHILADELPHIA, Nov. 6 (UPI) -- Tuesday's U.S. presidential election was just getting started when suspicion of irregularities sent lawyers into a Philadelphia courtroom, officials said.
Republicans protested to Pennsylvania's Court of Common Pleas that 75 of their poll watchers were being blocked from entering assigned polling places, ABC News reported.
Pennsylvania GOP Chairman Rob Gleason placed blame for the problem on President Obama's campaign.
"This was a shameless attempt from the Obama campaign to suppress our legally appointed Republican poll watchers in Philadelphia and they got caught," Gleason said.
Democrats countered that the issue revolved around credentialing and said they were trying to ensure that the inspectors had valid certificates.
On Monday U.S. District Judge Greg Frost was asked to stop some 25 Ohio counties from using voting machines that threatened to flip the outcome of the presidential election, Politico reported.
A suit filed by an Ohio college professor and Green Party congressional candidate charged the contract Ohio Secretary of State Jon Husted entered into with Election Systems of Omaha could allow changes on voting machine results by non-election board officials.
Ohio state officials called the lawsuit frivolous and said the company's software had been cleared by the U.S Election Assistance Commission.
Political observers say Democrats fear voter suppression on election day while Republicans are worried about vote fraud.
