What Newt says in the video of the interview is absolutely correct.
The way I read it, the Congress could abolish EVERY FEDERAL COURT IN THE US if they had the votes, except the Supreme Court. (This does not include state and municipal courts, for those of you with shitty reading skills) Sending a Congressional subpoena to a single judge a asking him to explain how his ruling fits with the Constitution seems a trivial matter in that light.
