Can you post a link to reliable documentation of that charge? I did note that they were married when he was 19 and she was 26, noting she had been his former high school geometry teacher. I did see the
Esquire article, but could not find a charge that she had inappropriate contact while he was a student under 18. I certainly do not condone contact between a teacher and under age pupil (or any high school student, for that matter.) I also note that Mr. Gingrich was an adult (19) when he entered into a valid marriage. I would further add that wife #2's comments in the Esquire article increase my concerns over Mr. Gingrich's suitability to be POTUS.
I would note that CNN posted an in-depth article on the first divorce, including links to the original court documents that I read in full. After reading the original documents I have and the quotes from those familiar with both divorces, I simply cannot trust Mr. Gingrich's character. There simply has to be an ethical conservative Republican candidate. For me, that is not Mr. Gingrich.
Each of us must do our own homework and then follow our conscience.
