Donald John Trump has done the seemingly impossible: He has managed to turn U.S. Attorney General Jeff Sessions into a sympathetic character.

The president has launched into another disgraceful Twitter tirade against the AG, chastising him for refusing to prosecute Hillary Rodham Clinton and for recusing himself from “the Russia thing” that hangs like a summer storm cloud over the Trump administration.

Trump continues to bash Sessions, apparently seeking his resignation so he can appoint someone to his bidding, which apparently includes sweeping the Russia probe away and prosecuting the candidate he defeated in the 2016 presidential election.

Sessions couldn’t possibly lead an unbiased investigation into the Russia matter, which involves questions into whether the Trump campaign colluded with Russian government goons in seeking to meddle in our electoral process. Sessions — Trump’s first declared supporter in the U.S. Senate — was a key player in the president’s campaign and his transition. Moreover, there remain questions about Sessions’s own Russia involvement.

Sessions is — or was — too close to the president.

As for prosecuting Hillary Clinton, the FBI found nothing on which to mount a “credible” prosecution; nor did congressional investigative committees; and nor did the Russian lawyer who met with Donald Trump Jr., Jared Kushner and former campaign chief Paul Manafort on the promise she had dirt on Hillary.

We are left now with the spectacle of the president of the United States shaming his AG and seeking to punish his former political opponent.

Which president has done such a thing? I can think of one: the current occupant of the nation’s highest office … the guy who continues to disgrace that office every single day.
