Rod Rosenstein is now under pressure to revise Mueller's special counsel appointment order. The formal appeal to amend it is based on the DNC hack now being thoroughly debunked in The Nation piece (and elsewhere). Rosenstein has no choice but to revise Mueller's appointment in order to narrow its scope.
Luckily, 14 focused. narrow questions pertaining to the most relevant matters were devised in committee and voted on as a recommended "second special counsel" by members of House Judiciary on July 27. The picture is from House Judiciary's letter to AG Sessions requesting that second special counsel.
These questions will formally supplant the existing and overly broad original scope, as well as the need for a "second special counsel," by instead charging the already-existing counsel to redirect their fact-finding efforts. Much of what is asked in House Judiciary's questions will overlap with what the special counsel has likely already been investigating.
This amended appointment order will formally require Mueller and his already-hired team to produce material answers to the 14 questions devised in committee by House Judiciary.
