Synonyms of coup d'état
: a sudden decisive exercise of force in politics
especially
: the violent overthrow or alteration of an existing government by a small group.
There is your answer. There was no violence, the challenges were in the courts. The unauthorized electors may or may not have committed a crime, I don't know as I haven't followed that story. Trump asking Pence not to certify the election is a none story. Everything I've read say's Pence's part of the process is ceremonial. At worst it would have ended up in court.
You can call it a coup if you like, but the simple reality is that Pence didn't have the power to reject the election results.
The person having the greatest number of votes for President, shall be the President, if such number be a majority of the whole number of Electors appointed; and if no person have such majority, then from the persons having the highest numbers not exceeding three on the list of those voted for as President, the House of Representatives shall choose immediately, by ballot, the President. But in choosing the President, the votes shall be taken by states, the representation from each state having one vote; a quorum for this purpose shall consist of a member or members from two-thirds of the states, and a majority of all the states shall be necessary to a choice.
And if the House of Representatives shall not choose a President whenever the right of choice shall devolve upon them, before the fourth day of March next following, then the Vice-President shall act as President, as in the case of the death or other constitutional disability of the President.
There is nothing there that says the VP can unilaterally reject the results. The entire thing was a non story because the conditions that allow it don't exist. Trump can and did make all the noise he wants, and Pence can pretend he did the honorable thing, but the end result was never in question as the rules governing the situation don't allow it.
