Every area of government has been corrupted by the Democrats.(Using the strength of their government office against political rivals)
We really don't how the court operates. I read recently the judges take 1 week turns as the active judge. Evidently they commute to DC for their turn. 3 of the 4 FISC judges approving the Carter Page FISA were from out of town. This would explain why 4 different judges signed off. I would expect the FISC court would have permanent staff members to handle the filings and most of the work. The judge then signs the request between shopping trips and sightseeing..
