Oh, how I want to believe Attorney General William Barr’s declaration that Donald Trump’s tweeting about pending criminal justice matters makes it “impossible” for the AG to do his job.

It’s just that whenever anything emerges with Donald Trump’s fingerprints on it, one must look for the rest of the story.

Barr told ABC News that he wants the president to stop tweeting about pending cases. He said the president is interfering with Justice Department officials doing their job.

Barr also said that his decision to recommend a lighter sentence for Trump pal Roger Stone than the one that prosecutors had sought had nothing to do with Trump’s tweet that called the prosecutors’ recommendation a “miscarriage of justice.”

However, I am left to wonder whether that is the whole truth. He could make that declaration without acknowledging any sort of pre-arranged agreement with Trump … correct?

I want to get back to the key point, which is that if Trump is going to continue to tweet and commend openly about matters that require discretion, that Barr’s job will remain an impossibility.

What does the AG do? He should just quit. Walk away. Go back to private practice. Leave the chaos and confusion to the next sucker who is willing to take the thankless job of reporting to the current president of the United States.

I had hoped that William Barr would be the grownup in a Cabinet full of sycophants and toadies. He has proven me wrong. Barr could restore some of that hope simply by quitting.
