I wonder if Collins has seen the testimony of Atkinson that Nunes referred to. Or, if it was kept partitioned and classified (she’s in the Senate, the testimony was to the House Intelligence Committee, IIRC).
That testimony reportedly made it clear that Atkinson ignored the legal advice he’d sought, consulted with Schiff or Schiff’s representatives, and changed pre-existing requirements to accept hearsay and to apply it to out-of-agency areas.
Those are the details I’d like to see.
