Who is Carol Brightling from Rainbow Six and what is their importance?

Carol Brightling is the former wife of John Brightling. Carol is the Senior Science Advisor to the President of the United States. The President does not share her radical environmental views, and she therefore finds conducting business with him extremely difficult. Her goals are not pure, however, as she uses her position to learn and pass classified information. She still has allegiance to her ex-husband and to his view of the state of the earth and humankind.
