Last week, special counsel Robert Mueller -- who had been appointed by the Department of Justice two years earlier to investigate the nature and extent of Russian attempts to influence the outcome of the 2016 presidential election and to determine, if those attempts did occur, whether the Russians had any willing American collaborators in the Trump campaign -- came to the cameras and announced his resignation.
The revelation last weekend by Michigan Republican Congressman Justin Amash that he believes the Mueller report accuses President Donald Trump of impeachable offenses has ignited firestorms in both major political parties on Capitol Hill. Amash's argument is simple and essentially unassailable, though his fellow congressional Republicans don't want to hear it and Democrats don't know what to do with it.
There was a time in American history -- nearly all of it up to the presidency of Woodrow Wilson -- when the federal government followed basic constitutional norms. With some unique and discrete exceptions, like the Civil War, Congress wrote the laws, the president enforced them, whether he agreed with them or not, and the judiciary interpreted them and assessed their compatibility to the Constitution. This is the separation of powers.
