A voter posted a video on YouTube showing the machine changing a vote for the president to a vote for his Republican challenger, The (Newark, N.J.) Star-Ledger reported. NBC News reported it confirmed the machine was taken out of service.
The Pittsburgh Post-Gazette said the machine was in Perry County. Department of State spokesman Ron Ruman said the machine was fixed and put back into service.
The 18-second video was posted by "centralpavoter." It features a finger hitting the button for Obama several times and the machine registering the action as a vote for Romney.
"I asked the voters on either side of me if they had any problems and they reported they did not," the poster said in the YouTube description. "I then called over a volunteer to have a look at it. She ... calmly said, 'It's nothing to worry about, everything will be OK' and went back to what she was doing. I then recorded this video."
