Nope, not a coup attempt at all headed by the Trump admin as this text from Jim Jordan, a sitting member of Congress, sent to Mark Meadows proves:
""On January 6, 2021, Vice President Mike Pence, as President of the Senate, should call out all electoral votes that he believes are unconstitutional as no electoral votes at all -- in accordance with guidance from founding father Alexander Hamilton and judicial precedence. 'No legislative act,' wrote Alexander Hamilton in Federalist No. 78, 'contrary to the Constitution, can be valid.' The court in Hubbard v. Lowe reinforced this truth: 'That an unconstitutional statute is not a law at all is a proposition no longer open to discussion.' 226 F. 135, 137 (SDNY 1915), appeal dismissed, 242 U.S. 654 (1916). Following this rationale, an unconstitutionally appointed elector, like an unconstitutionally enacted statute, is no elector at all."
Promoting not counting the electoral votes Pence thinks are 'unconstitutional' for some reason is no attempt at overturning the election at all.
