Why a High Price for Swallow Impeachment?

   A recent article -- don't remember which paper -- suggested impeaching John Swallow could be a very expensive process.
   I wonder why. Perhaps it will be, but I do believe we should question why. If the Legislature brings in witnesses, is there a price? Are subpoenas that expensive? Are we assuming there would need to be investigation done other than the witnesses brought in? Are we paying lawyer fees for lawyers to be present? Just what is it that is to cost so much?
   Well, I do think if a high price is expected, we should be told why. And, if we don't agree with the expensive items -- lawyers, or whatever -- we should do the impeachment without them. If this is to be too expensive, it almost seems that that, itself, is a scandal.
