Who do you think would fit the bill? Whoever that person would be, they would need the support and encouragement of the President and be allowed to 'go after liberal criminals in all strata of society and at all levels.'
Would the President support and encourage the prosecution and jailing of criminal elites who are serving or have served in: government, media, education, organizations, business etc? I have my doubts. Washington's way is to thrown a few underlings under the bus but higher up elites are off limits. Republicans hold the Senate, House and Presidency and still there is no will to put people like the Clintons, Obama, Holder, Koskinen .... in jail.
