There was reporting that the indictment was coming early in the week, so there must have been leaks that Halligan was presenting to a grand jury.
Back in 2020, they were obsessed with discrediting Comey. The ONLY "smoking gun" they could come up with then was the notion that Comey "authorized" McCabe's leak of the status of the investigation into the Clinton Foundation in 2017.
In response to Sen. Ted Fucking Cruz (to use his full name), Mr. Comey stated simply, and by all subsequent investigation, truthfully, that he had never authorized a leak of information.
It was a pretty simple set of facts to present, so wouldn't take long, particularly because what Halligan presented undoubtedly excluded the fact the accusations had already been investigated and dispensed with, or the fact that her predecessor was fired for refusing to pursue an indictment because there was no "there" there.
AI summary:
Leak source and subject: In 2017, it became publicly known that then-Deputy FBI Director Andrew McCabe had authorized a leak to a Wall Street Journal reporter in late 2016 regarding the status of the investigation. McCabe was subsequently accused of lying to the DOJ inspector general about authorizing this leak, which eventually contributed to his dismissal from the FBI in 2018.
Inspector general's conclusion: A later investigation by the DOJ inspector general found that while McCabe had shared information, FBI rules allowed the deputy director to speak with the media without authorization. The report also concluded that former FBI Director James Comey had not authorized the leak.
