Tell them to resubmit the info about Steele's supposed dislike of Trump to FISA [View all]
...and see what the judges think.
It's not a given that those weak claims about Steele's politics would cause the FISA judge to negate the warrant granted against Carter Page. It's more likely that it wouldn't move the judge, at all. Reliable info comes from supposedly biased sources all of the time.
It's not likely the judge's opinion centered on Steele's reputation. Probable cause weighed by the court in determining whether to grant the FISA application wouldn't rest on Steele's political views or associations. Indeed, the FBI investigation and original application for a warrant predated the time the Steele dossier was obtained by the FBI.
As of now, the FISA court has declined to respond.
...even the Nunes memo admits the FISA court was looking at more evidence than the Steele dossier:
