David Hardy says there are options to be considered now that Holder has been found in contempt of Congress:
The House sends out its Sergeant-at-Arms to arrest the defendant, he is tried on the spot, and the House decides whether to convict.It is a little bit of a surprise to me but the Capital has a dungeon just for such purposes. And I find it interesting and very pleasing that:
…presidential pardons appear not to apply to civil contempt procedures such as inherent contempt because it is not an “offense against the United States” or an offense against “the dignity of public authority.”
A commenter at the David Hardy link above suggests that leaving AG Holder out of durance vile would be a better strategy, but I think I disagree. The advantage of asking Holder himself, "what did the president know and when did he know it", isn't measurably more effective than is responding to efforts to obtain his release with the same query I think.
One added attraction of sending out the Sergent-at-Arms of the House (with as many Capitol Police as needed for back-up) to arrest the AG is the really strong potential for all the various DOJ gun toters to actively oppose their boss being given the good news. I can see the headlines now; "House Swatties No-Knock AG's Office", "OK Corral, D. C.", "Blood In The (Capitol) Streets".
So, how do you say "snark" in spanish Mr. Calderon?
