I can't easily check the transcript of the Benghazi hearings, or her campaign, so I really can't comment on whether or not she's made similar claims in the past.
I will say if the complaint is that by specifically limiting her comments about loss of lives TO just the military campaign, and therefore intentionally omitting the deaths from the terrorist attacks in Benghazi, that's fine. I am pretty sure no candidate will voluntarily bring up their biggest foreign policy failure, at least in the eyes of the public, but it's true the approach is intended to put the best light possible on her record, which is what I expect we'd all do in what amounts to a job interview.
To me it's kind of like when Bush II or his surrogates and supporters say words to the effect that the War on Terror has kept us safe from domestic attacks, isn't actually claiming that 9/11 didn't happen and we lost no lives on that day. But that's how the right wingers in this discussion interpreted what she said, and it's just false, especially since she clearly limited her comment to "in that action."
And I wouldn't expect the Bush or his people to say, "Except for the thousands of lives we lost on 9/11, the War on Terror has been a success!" But that's what people are demanding of Hillary or else she's "lying" about Libya.
