The problem is that for all we or anyone else knows, Romney doesn’t see it as a significant issue or one worth discussing. I think he can bring it up without coming across as politicizing it. He simply needs to say that others have raised relevant questions that have a bearing on whether the Americans in Benghazi needlessly died and that those questions could be answered right NOW by the administration. Then tell us what the questions are.
Exactly "for all we or anyone else knows." You, as anyone else, do NOT KNOW if he sees it as being significant, or not. Just to answer THAT question: I am sure he sees it as majorly significant, but he CANNOT speak of it yet.
