There must be some (DARNED) good reason why the several congressional committees don’t:
1) Clean up the Capitol Jail,
2) Issue Subpoenas for the immediate delivery in person of the required documents,
3) Have the Capitol Police standing at the rear of the hearing room,
4) Toss the DoJ & FBI goons in jail as soon as it is determined that even ONE of the required documents is missing or redacted.
Don’t even think about letting them out until they get their underlings to comply.
Repeat steps 2-4 until full capacity is reached or full compliance is obtained.
There is. The FBI has dirt on all of them.
