According to the Des Moines Register, "An Iowa State University lecturer was arrested Thursday morning for public intoxication."

Campus police were called to the classroom of 56-year-old Gordon Night. When they arrived, they smelled alcohol on his breath and were concerned about his behavior. Night refused to take a breath test. He was arrested and charged with public intoxication.

This isn't Knight's first problem with alcohol. According to Iowa online court records, this is his third alcohol-related arrest in the past year.
