The Illinois government agency that looks into complaints against doctors announced it will lay off investigators starting Tuesday and warned of yearlong delays in physician licensing because the Legislature didn't act to bail out the medical watchdog unit. In a letter being sent to doctors Thursday, officials from Illinois Department of Financial and Professional Regulation pin the blame on the Illinois State Medical Society for lobbying against legislation to transfer $9.6 million to keep the program going. The Associated Press obtained a copy of the letter on Wednesday.
