I think Issa has to get Boehner's approval.
You are most likely correct on that.
Neither Issa nor Boehner can arrest anyone. What they could do - and what Issa is trying to build a case for - is appoint a special prosecutor, who could investigate and then charge. Then these people, if charged, could be arrested and tried.
Congress has the authority to appoint a special prosecutor. The Justice Dept. also has that authority, but we certainly don’t want anybody Holder would appoint. Look how he has tried to cut off other investigations by appointing a “special prosecutor,” sometimes from the investigated agency itself!
“There is enough to arrest people.”

Boehner has to be stonewalling Issa’s investigations. Almost a certainty.
