An Iowa State University lecturer arrested for being drunk in class has been placed on paid administrative leave. ISU officials have opened a faculty misconduct investigation into Philosophy and Religious Studies instructor Gordon Branch Knight. He was taken into custody last Thursday after someone anonymously reported he was slurring his speech during class. Police say Knight had bloodshot eyes and strong smell of alcohol on his breath, admitting he had drank and taken sleeping pills the night before. He refused a field sobriety test and was charged with public intoxication-second offense. Knight's initial court appearance is later this week. Knight is not allowed on campus while on leave.
