This story is impossible to either validate or invalidate. Perfect for the liar in chief to tell.
Political can go back to 1969 to produce a lie about Dr. Ben Carson, but won’t go back to check on this Hillary lie. Gee what a surprise!
The story as reported about 1992 was she was quoted as trying to join the Marines. I remember when that was a major story in the Arkansas newspapers.
As to Bosnia... I currently work with a guy who was greeting her plane. No hostile fire occurred.
