Has the FISA Court done anything about being lied to? No. Given that Barr isn’t going to anything either, unfortunately. The Deep State are playing a beltway shell game right now.
I’m going to wait until the dust is settled before I make any postmortems on this.
“Has the FISA Court done anything about being lied to?”
Why would they? There’s about a 95% chance they were complicit. Remember, FISA is overseen ny SCOTUS Roberts, and it’s pretty obvious where his loyalties are. (Hint: Not with us.)
