Your cynicism may well be justified. At the same time, one wonders what our House and Senate committees will do to follow up on their subpoenas.
As of yesterday, Sensenbrenner's office told me 'there is no talk' in the House of enforcing their subpoena.
More Showmanship?
What? Well, gee, too bad nobody knew sooner that congressional subpoenas can just be sloughed off. Would have saved lots of people a lot of time, trouble and expense. (Do I really have to /sarcasm? Some people's sarcasm meters seem to be malfunctioning on these threads.)
