PHOENIX - Sen. Scott Bundgaard resigned from the Arizona Legislature on Friday, stepping down shortly before he would have testified to the Senate Ethics Committee on whether he should be disciplined for a February domestic incident involving a former girlfriend.
The resignation ends an ethics case that could have resulted in a recommendation that the full Senate issue a letter of reprimand, formally censure Bundgaard or expel him.
Bundgaard's ex-girlfriend, Aubry Ballard, testified Thursday that he struck her twice and threw her cellphone out the window while they drove and then stopped on a Phoenix freeway and pulled her out of his car.
Ballard said she reacted to being hit in the chest by slapping Bundgaard in the face. Both had cuts and bruises after the Feb. 25 confrontation, she said.
Ballard testified that the confrontation followed an argument over his decision to take dancing lessons while failing to take the time to get counseling for a previous physical altercation.
Bundgaard wasn't arrested at the scene because he claimed legislative immunity, which bars arrests of lawmakers for most charges while the Legislature is in session.
Phoenix police officers testified Thursday that he demanded to be released from handcuffs after they detained him and reeked of alcohol but refused field sobriety tests. He also bluntly denied drinking, a sergeant testified -- a statement the sergeant said he "absolutely" didn't believe.
Bundgaard would have been arrested on possible domestic violence charges and suspicion of DUI if not for the immunity law, the sergeant and an officer testified.
Bundgaard has denied assaulting Ballard. He later pleaded no contest Aug. 16 to a misdemeanor endangerment charge under a plea agreement. It included dismissal of an assault charge and a requirement that he get domestic violence counseling.
The incident prompted fellow Senate Republicans to replace Bundgaard as Senate majority leader in March.
Bundgaard, a Peoria Republican, wrote Friday in his brief letter to the Senate president that he was resigning "with deep regret." He didn't specifically mention the ethics proceeding or the confrontation with Ballard.
Senate Majority Leader Andy Biggs, a retired attorney and an Ethics Committee member, said evidence presented during the hearing was "pretty damaging." Bundgaard clearly wanted to tell his side of the story but he seemed to have concluded he couldn't recover politically, Biggs said.
Bundgaard attorney Andre Merrett told the committee on Thursday that his client regretted his role in the altercation but shouldn't be punished by the Senate because he never intended to harm Ballard or put her at risk.
But the lawyers serving as the committee's independent counsels said expulsion would be warranted because Bundgaard assaulted Ballard and lied to police and others about his actions and claimed legislative immunity.
"In this case, you not only have domestic violence, you've got obstruction of justice," attorney Cory Langhofer said Friday, following Bundgaard's resignation. "Expulsion would have been the only appropriate remedy."
The Maricopa County Board of Supervisors will appoint a replacement to fill the Senate vacancy. The replacement must be a Republican.
Bundgaard was elected to the state House of Representatives in 1994 and the state Senate in 1996, serving there for six years before staging an unsuccessful run for the U.S. House in 2002.
Following the congressional campaign, then-President George W. Bush appointed him to the White House Commission for Presidential Scholars and the Presidential Scholars Foundation Board. Bundgaard returned to the Senate in 2011.
Bundgaard didn't immediately respond to phone and email messages seeking comment on Friday. He was to have testified in the afternoon, but the hearing was halted after a lunch break when Merrett told the committee that further proceedings weren't necessary.
Another Bundgaard attorney, Shawn Aiken, later said his client decided during the break to resign. Aiken said he believed the hearings were going well considering the defense hadn't yet put on its case.
Ballard said she hoped Bundgaard's resignation would allow her to put the "unfortunate assault in the past and to get on" with her life. A statement she issued through a publicist thanked law enforcement officials and the committee.
Bundgaard's resignation was the best move for him, his family and the Senate, said Senate President-designate Steve Pierce. It eliminated what would have been a distraction at the beginning of the Legislature's 2012 session, he said.
The resignation also shows that the Senate holds its members to account, said Sen. Steve Gallardo, a Phoenix Democrat.
"No one is above the law," he added.
Bundgaard wrote to State Senate President Steve Pierce:
With deep regret, I hereby resign my seat as Arizona State Senator for Legislative District Four.
It has been my honor and pleasure to serve the people of Legislative District Four for this past year.
