least conconcern of a political nature and you mentioned rosenstein may have to step in and pull back the reins if mueller goes too far. imagine if the president were to make good on his threat, a hyperbolic as it may have been intended, don't go after my money. that's too far, then what would happen in this situation? not legally but the optics and the politics and the realities of rosenstein saying to mueller stop doing that or the president saying mueller's gone too far, step in. what would that mean? >> it would be a complete political cunipgz in washington d.c. but it would also i think be consistent with the constitution. we cannot have unaccountable prosecutor that pursues whatever they want to pursue without any relationship to the people
