Judge Greer is certainly setting himself up for a confrontation with the Congress.
It's not likely one that he is going to figure prominently in history as having a laudable role. In my opinion, he did himself harm by ordering the removal of the feeding tube in the face of the subpoena. Even if he didn't agree with the committee, he still would have been better off to postpone the execution rather than acting contemptuously.
Any constitutional legal eagles here? Wondering what the legal dynamic is for Greer and the healthcare providers who were subpoened and told not to remove her feeding tube and then did. Would their being in contempt of Congress be truly a weighty matter and truly punishable?
