I believe Weismann’s boss, Sally Yates signed one of them...
Sure seems like I have heard Bongino saying exactly this for a year now... But maybe I am wrong.
Here is another article that I found trying to confirm it.

and this one talking about Sally Yates as being one of the five in deep trouble over it.

Former FBI Deputy General Counsel Trisha Anderson testified to the House Judiciary and Oversight committees in August 2018 about the “unusual way” that the first FISA request was handled, with approval coming from Yates and then-Deputy Director of the FBI Andrew McCabe before it reached her desk, contradicting the normal path that the FISA applications take and leading her to not feel the need to second-guess her higher-ups.
The April 2017 FISA renewal was approved by Comey and by Dana Boente. Boente is the only signatory still remaining in active government service, working as the Trump administration’s top lawyer at the FBI starting in January 2018.
The June 2017 FISA renewal was approved by McCabe and Deputy Attorney General Rod Rosenstein.
