I don't know if you recall it, but not quite 44 years ago, Nixon "fired" the Watergate prosecutor, Archibald Cox. This lead Attorney General Elliot Richardson and Deputy Attorney General William Ruckelshaus to resign, and was known as the Saturday Night Massacre. A poll conducted the next day determined that a majority of those polled favored impeaching Nixon. Nixon resigned rather than face impeachment and a trial before the Senate, on August 8, 1974--not quite 43 years ago.
On that Saturday night, Cox issued a statement: "Whether ours shall continue to be a government of laws and not of men is now for Congress and ultimately the American people [to decide]."

I can think of nothing more delightful than that President Plump would attempt to fire Mueller. Less than a month after the Saturday Night Massacre, a Federal District judge found that firing Cox was illegal without a finding of extraordinary impropriety.
Come on, Plump, do it, do it!
