RR looks more suspicious here - what if the highly redacted portion is another sequence of people + expansion ala Manafort for 2016 Russia + election AND 2005 Ukraine stuff, person #2 for 2016 Russia + election AND whatever they want, person #3 for 2016 Russia + election AND whatever else they want, etc.
But, in the end RR does not have the right to authorize anything beyond the Trump/Russia connection. Anything outside of that would have to come from Sessions, IMO.
