Metro State College is investigating a professor who asked students to write an essay critical of Republican vice presidential candidate Gov. Sarah Palin.
One student said the instructor singled out Republican students in the class and allowed others to ridicule them.
Instructor Andrew Hallam asked students to write an essay to contradict what he called the 'fairy tale image of Palin'
Metro State officials are investigating claims of bias, harassment and bullying.
Hallam declined an interview with CBS4. He has revised the assignment.
