Analysis: Constitution Requires Sessions to Dismiss Mueller from Non-Campaign Cases

"….Rosenstein could not appoint Mueller to any investigation outside the scope of the 2016 campaign since Sessions did not recuse himself for anything outside the campaign. [T]hat would mean Sessions himself has exclusive authority to appoint a special counsel for non-collusion charges, and Sessions has taken no such action. Sessions himself should make that clear to Mueller, rather than await court resolution. Doing so would remove three of the four areas of inquiry from Mueller’s requested interview with President Trump."
