I thought the "revenge" was meant to be Congress finding out why their subpoenas were ignored, and doing something about it, not going after judges because they didn't like their ruling.
What is the saying, "If you don't use it, you'll lose it." If the Congress doesn't protect their subpoena rights, if the courts ignore the power of Congress, then Congress will lose it.

I can understand that... but then again, it's hard to "respect" a power of subpoena when it's being used in a disrespectful way.
