I'm not sure that is true. I believe there has to be a special investigator/prosecutor like Durham to bring indictments like he just did against Michael Sussmann.
According to the indictment, Sussmann -- a prominent cybersecurity lawyer whose law firm Perkins Coie worked for Hillary Clinton's 2016 campaign -- lied at a September 2016 meeting with then-FBI General Counsel James Baker in which Sussmann shared information about possible connections between the Trump Organization and a Russian bank.
IIRC, the head judge at FISA gave the FBI the riot act for not thoroughly vetting their witness/evidence when applying for warrants. The problem was until now, even the FBI "supposedly" didn't know Sussmann was lying. I believe more will fall, but not Comey or Hillary because they now have an excuse in Sussmann.
Mark Levin: It's time for FISA court judges to face scrutiny
Most notable to me in his words is that the FISC judge he filed an amicus brief with lied to him in her response.
