Colbert consults businesses on human resources issues and he says it appears CMS may have a big HR problem with Morrison.
"So if it is related to his communication abilities, to his management style, I'm sure there were multiple complaints," said Colbert.
The investigation into Morrison's resignation is closed to the public, and district leaders won't comment just yet.
"We are are not in a position to answer questions," said Ann Clark, interim Superintendent for CMS on Wednesday.
Colbert says keeping everything confidential is normal when dealing with a major transition of leadership, but he says since Morrison is the leader of not only thousands of employees but also the education of children, his private details may need to come out soon.
