Well, why didn't he?
Boehner can have anyone arrested for anything within the precincts of Congress. He's the Speaker.
I've made an argument several years back that the Congress could probably hold a trial and execute someone ~ although it's unlikely they would do so for anything less serious than treason. Someone might come up with a set of the Rules of the House and the Rules of the Senate and read them expansively to see just how bad it is.
