They are listed from left to right on the video as Pregerson, Tallman, and Nguyen, IIRC, but at one point the judge on the left speaks of the middle judge as Pregerson. I think Tallman is the one on the left.
So is he the one on the FISA court, or is Tallman? I mean I'm impressed with the whole panel and it's a hilarious proceeding, but I'd be interested to see this point cleared up, and Wikipedia's list [0] doesn't mention either. (I don't really know where else to look.)
Tallman is on the appellate level of the FISA court [1], which is why his name doesn't appear on that Wikipedia page. Pregerson isn't on the FISA court at any level.
Fun fact: Tallman, the judge in the middle with the great stories - is one of three judges who sit on the FISA court
