If we are fortunate, Issa wioll be calling Ham and Gibson in on Benghazi hearings. Whether they are bound by military secrecy on classified matters is the issue.
It would be so simple otherwise to get truth from them both.
There were hearings, for example, on the attack on Pearl Harbor at the start of World War II, by Congress.
So this is not without precedence...
Some folks here on FreeRepublic have commented that F16 fighters could have been over the Benghazi compound without the need for air re-fueling.
If Issa et al. do this right, they can ask yes or no questions that can be pre-screened for televising.
This might entail a closed door hearing beforehand to protect secrecy.
