While I am sure people will try, my initial impression is that with all the redactions it is going to be very tough to figure out the full scope of information supporting the Court’s repeated finding of probable cause to believe that Carter Page was an agent of Russia. There is a mention of two Russians, one of whom pleaded guilty to being an unregistered agent of a foreign government and was sentenced to 30 months, but even that is disconnected from the redacted discussion that precedes it. Substantively, the government seems to have hewed as closely to the prior disclosures as it could in applying FOIA.
But it is worth noting that—and as the Democrats previously pointed out—the judges who signed off on these four FISA applications were all appointed by Republican presidents, including one George H.W. Bush appointee (Anne Conway), two George W. Bush appointees (Rosemary Collyer and Michael Mosman) and one Reagan appointee (Raymond Dearie). I know some of those judges, and they certainly are not the types to let partisan politics affect their legal judgments.
