:This is a reference to the exchange with a particular Republican senator and her response, which was the most replayed part of five hours of hearings.  Now we have a subarticle, Hillary Rodham Clinton's tenure as Secretary of State, that goes into much more detail, and as part of three paragraphs that cover the January 23 hearings, contains this text: 
 ::Senator Ron Johnson, a Republican associated with the Tea Party movement, questioned her repeatedly on a different aspect, whether Ambassador to the UN Rice had misled the public after the attacks. This line drew the fieriest response from Clinton, who with voice raised and fists shaking, responded, "With all due respect, the fact is we had four dead Americans. Was it because of a protest or was it because of guys out for a walk one night decided they'd go kill some Americans? What difference, at this point, does it make? It is our job to figure out what happened and do everything we can to prevent it from ever happening again, senator."[252] 
 :But we are constrained for space in this main biographical article, and the sentence above is an attempt to summarize this succinctly.  But I am open to other suggestions for how to word this. And yes, you are right, her general response to Benghazi has been that questions about security lapses leading up to the attacks are a legitimate area of inquiry (and she agreed with all the points made and changes suggested by the Accountibility Review Board), while the questions about the Rice comments on the Sunday talk shows is a ridiculous made-up political issue only.
