Title 2, Section 192 of the U. S. Code says that refusing to testify or produce documents in response to being summoned by Congress is a misdemeanor punishable by fine and imprisonment. It does not equivocate. It doesn't say it's a misdemeanor unless the President prefers someone not to testify. Section 194 says that when someone violates Section 192, a U. S. attorney has the duty to bring the matter before a grand jury. It doesn't say that this duty only exists unless the President prefers the law not to be enforced.
I refer, of course, to the violation by Mister Bolten and Miss Myers of Section 192, and the refusal by Mister Taylor to perform his duties under Section 194. Surely you are aware that there is no hope of upholding the rule of law if those who are duty-bound to enforce laws choose to enforce them selectively, at the whim of those against whom they would be enforced. Will you now commit to perform your duty as attorney general and uphold these laws, or will you explain to us, assembled here in this room, why you and Mister Taylor should not be prosecuted for obstruction of justice, and why anyone should believe that you are serious about eliminating corruption when it is your own department that is protected from scrutiny by your continuing failure to enforce the law?
If you know anything about how these sessions are run, or how one gets to ask questions, please do tell.
