I personally contacted Lynn Sweet, who wrote the 1993 article and she is still working for the Sun Times and now their chief correspondent in Washington DC. I spoke with her twice on the phone and questioned her about her sources on the article. Unfortunately, too much time has passed and she can no longer remember how she determined that Dorothy Rodham arrived "early", or even what exactly "early" means. Ms. Sweet did not interview Hillary or her mother for the article but she does (vaguely) remember reading the 12 hour labor info from some sort of document, which she remembered as the birth document. But again, she can provide no notes of how she came up with this data and we are not likely to get any more info on this in the future (although she said that she would call me if she could remember anything else).
