Oh, the irony. During the House Judiciary committee impeachment hearing, Republicans complained that impeaching Donald Trump for obstruction/contempt of Congress was a threat to the separation of powers and that disagreements between the Executive branch and the Legislative branch should be settled by the Judicial branch.
The irony? Donald Trump believing he is king and above the law is the greatest threat to the separation of powers this country has seen since the South seceded from the Union.
What the GOP seems to be missing is that permitting a president to obstruct justice, put him or herself about the law and/or to violate the oath of office with impunity, sets a precedent that could potentially allow a future president with a different political persuasion to do the same.
