Scott Bundgaard, the Arizona state Senate majority leader, was involved in a domestic violence dispute with his girlfriend, but was not arrested because he has legislative immunity, police said on Saturday. Republican Bundgaard's girlfriend, Aubry Ballard, 34, was booked for domestic violence assault, police said.
Phoenix police responded to a report on Friday night that Bundgaard was pulling Ballard out of a car stopped next to the median on State Route 51.
When officers arrived, they encountered Bundgaard and Ballard, and saw both had marks on their bodies showing they had been in a physical altercation, said Police Department spokesman Sgt. Tommy Thompson.
Bundgaard and Ballard were both detained, but Bundgaard told officers that under Arizona law he is immune from arrest while the legislature is in session, police said.
