This never happens but here is the report - https://int.nyt.com/data/documenthelper/6600-fisa-court-demands-answers-fro/87f1132ddc399b0c99b1/optimized/full.pdf#page=1 - from the presiding FISA judge stating that the FBI had provided false information and had withheld information from FISA judges in order to get a warrant granted to wiretap Trump Campaign officials.
Here's some quotes from the above statement.
The FBI responded by saying that their FBI Director (A Trump appointee) is taking appropriate action against those that had withheld information and provided false information and that they've implemented a 40 point corrective plan to fix this from happening again.
I doubt anything will really come out of this, but I guess we'll see. Just pretty crazy to see the FISA court come out like this, as they never do.
