(AP)  A lawyer for a state senator accused of taking an SUV and trailer from a stranger's home and  driving it while drunk says there are "medical explanations" for his client's behavior.   Idaho Senate Republican Caucus Chairman John McGee was arraigned Monday in Idaho's 4th District Court. He faces two charges: misdemeanor drunken driving and taking a vehicle without the owner's consent, causing more than $1,000 damage, a felony.  The 38-year-old McGee was arrested early Sunday after police say he took the Ford Excursion and cargo trailer from the Boise home of a "complete stranger." They say a blood-alcohol test showed the four-term lawmaker had been drinking.  McGee made his first appearance via video. His attorney, Scott McKay, said during the hearing there are "medical explanations" for McGee's actions that would negate any criminal liability in the case. He declined to elaborate.  McGee's bond was set at $5,000.
