I really don’t understand what the House is doing here. The judge is a jerk, but I find it very hard to believe that he would reach a different view of the merits than prior judges from both parties. All I would expect is a ruling that might cause Bolton to testify. Bolton talked to Trump. They want Bolton under oath.
My guess is that they fear Judge Leon enough that they prefer to just let the multiple rulings from the DC Cir and 2nd Cir do the talking, and expect to get relief quicker from the DC Circuit (and a binding ruling at that) from the currently pending case involving the McMahon Subpoena which was upheld by Judge Jackson.
It is also possible that they want the case before Leon over with. The risk of leaving it before Leon is that defendants would challenge all future subpoenas and then ask that they be treated as a related case to the one before Leon, getting all future litigation transferred to Leon. Perhaps it has been worth giving up Kupperman in return for Leon letting go, so that any future subpeona challenges can go to Judge Jackson (House would try that) or are randomly assigned.
That said, I don’t think that is going to get Bolton to testify, who is who they want to testify…
So sort of scratching my head…
