Excepts from an article on the Atlantic by Jonathan Rauch

When I step back to look at the legacy of President Donald Trump, a surprising conclusion emerges: He has substantially altered the Constitution. His changes aren’t formal, of course. But his informal amendments are important. If left to stand, they threaten to make Congress an advisory body and give carte blanche to rogue presidents.
Amendment 1. No president shall be removed from office for treason, bribery, or any other crime or misdemeanor, no matter how high, should a partisan minority of the Senate choose to protect him.
Amendment 2. Congressional oversight shall be optional. No congressional subpoena or demand for testimony or documents shall bind a president who chooses to ignore it.
Amendment 3. Congressional appropriations shall be suggestions. The president may choose whether or not to comply with congressional spending laws, and Congress shall have no recourse should a president declare that his own priorities supersede Congress’s instructions.
Amendment 4. The president shall have authority to make appointments as he sees fit, without the advice and consent of the Senate, provided he deems his appointees to be acting, temporary, or otherwise exempt from the ordinary confirmation process.
Amendment 5. The president shall have unconstrained authority to dangle and issue pardons for the purpose of obstructing justice, tampering with witnesses, and forestalling investigations.
