Posting isn't something I do often, in fact, this is my first. I hope you find it informative and thought provoking.
Sharyl Attkisson is an... "Investigative Journalist who tries to give you information others don't want you to have. What you do with it is your own business. Do your own research. Seek advice from those you trust. Make up your own mind".
