Benghazi politics often get more attention because of the personalities involved. But there is also a policy divide.

Republicans say they do not yet have a full picture of three critical issues:

• Why the warnings didn’t reach the point where the State Department either sent more security help or ordered the Benghazi mission closed.

• Why, especially given the weeks of threat warnings, there was no viable military option to assist the State Department personnel at the Benghazi mission and the predominantly CIA-run annex that came under attack later same evening and where two of the four Americans were killed.

• And why, nearly a year later, no one has been brought to justice.
