A Senate Confirmation Hearing will require questions. If there are more Rep. Senators than Dems, the questions will be interesting. If the Rep. Senator's were paying attention during the GHWB funneral, then the questions will be very specific. This confirmation could take a very long time, this leaving the acting AG in control. I think there is a 240 day limit for an acting AG. Anyway, that is a long enough time to bring many to justice.
My belief is that anyone who was running interference for the Bush drug running cartel won't make it through confirmation. That would be Barr and his side kick North.
