As the article describes, the marriage is referred to in the Hawaii index of marriages, is referred to in the record of the 1964 divorce papers and is referred to in various INS documents from those years.
It’s in the divorce papers. But that doesn’t make it real. If it was real, then where is the marriage license, at what church or civil office did the wedding occur, who performed the ceremony?
Yes, “referred to in INS docs” - which I have read - as in “Obama says he is/got married to American”. The references are to his oral allegations, the references are not to a document proving that a marriage took place.
