Linda Tripp advised Monica Lewinski to save the stained dress and tape conversations with Clinton, In effect she saved Lewinski's life. Tripp also reported the thefts of White House gifts by the Clintons. Thefts which still havent been investigated thoroughly.
Tripp was a brave woman. She probably saved both of their lives. I believe Linda was also one of the last people to see Foster alive.
If you have not done so please read "Ron Brown's Body". I can't remember the author right now, but he presents compelling evidence that Brown and all aboard his plane that "crashed" in Croatia were murdered. I know it sounds crazy, if I had not seen the author on Cspan I never would have known about this book. Like Mark Lane and the JFK assassination books in the mid 60s it's not the kind of book the NYT is going to review. The book is not easy to find, my local Barnes and Noble had one copy on hand several months ago, but recently, those who wanted it had to special order.
