What Did The FBI Know Prior To January 6?

What was known by the FBI in the days and weeks preceding the Capitol hack on January 6? Is it possible that the Justice Department is breaking Brady laws?

Because they had deployed FBI confidential human sources there, Kash Patel contends that Christopher Wray was lying when he said that the FBI lacked any verifiable or credible evidence that January 6 would occur.

The Department of Justice is actively prosecuting individuals even though they have not thoroughly researched the case and are aware that some of the defendants they are now prosecuting may benefit from the information available.
