(CNN) – Alaska Sen. Lisa Murkowski is taking aim at rival Joe Miller amid news the Tea-Party backed Senate candidate lied to his superiors regarding improper use of government computers in 2008, according to documents about disciplinary actions taken in the matter and obtained by several Alaska media organizations.
"I believe Alaskans disagree with the severity of his actions and they expect more out of all employees serving in government positions – especially out of someone running for the United States Senate," Murkowski said in a statement.
"The bottom line is Joe cheated, he lied, tried to cover it up, lied again, then finally got caught and had to admit it, just as he lied to Alaskans when he initially denied any problems with his employment at the Borough, claiming his record was 'exceptional' and 'second to none,'" she added.
The documents' release came after a series of news organizations, including the Associated Press, the Alaska Dispatch, the Fairbanks Daily News-Miner and the Anchorage Daily News made an open records request and initiated a subsequent lawsuit.
Miller, who in 2008 worked as a part time attorney to the Fairbanks North Star Burough, told superiors that he initially lied when asked about his use of government computers for political activities. Later admitting to improper use, Miller told his superiors there was "no excuse" for his actions and was willing to accept appropriate punishment for them.
"I lied about accessing all of the computers. I then admitted about accessing the computers, but lied about what I was doing. Finally, I admitted what I did," Miller said in a statement to his manager.
Miller was suspended for three days and required to participate in an employee assistance program.
According to Miller's written statement at the time, the future candidate used government computers to anonymously take part in an online political poll and then cleared the computers' caches in an effort to cover up his actions. Miller's actions were part of an effort to oust the state's GOP chairman ahead of party convention.
Miller left his job entirely later for reasons he maintains had nothing to do with the incident.
