Republican Senate nominee from Alaska Joe Miller admits that he was once disciplined for using government computers for political purposes.

Miller faced incumbent write-in candidate Lisa Murkowski and Democrat Scott McAdams in a debate Sunday.

"Scott is not ready to lead," Murkowski said to mixed audience reaction. "Joe is not fit to lead."

"I have been leading this state for eight years and I will continue to do so, bringing the seniority I have built, the work ethic that I have built, and the passion for a state that I love," she said. "Fill it in. Write it in."

During the course of the debate, Miller was forced to concede that he was once disciplined for violating policy while working as an attorney at the Fairbanks North Star Borough. The candidate claimed that he had been docked three days pay for using a computer to take a private poll during his lunch break.

Miller told CNN last week that the incident had nothing to do with why he eventually left the job.

"Is this a fair statement, in your view that at the time this happened, you were disciplined for something, but it had nothing to do with why… you left the agency down the road?" asked CNN's John King.

"Absolutely," replied Miller.
