Two days before the January 6 insurrection, the Trump campaign’s plan to use fake electors to block President-elect Joe Biden from taking office faced a potentially crippling hiccup: The fake elector certificates from two critical battleground states were stuck in the mail.

So, Trump campaign operatives scrambled to fly copies of the phony certificates from Michigan and Wisconsin to the nation’s capital, relying on a haphazard chain of couriers, as well as help from two Republicans in Congress, to try to get the documents to then-Vice President Mike Pence while he presided over the Electoral College certification.

The operatives even considered chartering a jet to ensure the files reached Washington, DC, in time for the January 6, 2021, proceeding, according to emails and recordings obtained by CNN.

The new details provide a behind-the-scenes glimpse of the chaotic last-minute effort to keep Donald Trump in office. The fake electors scheme features prominently in special counsel Jack Smith’s criminal indictment against the former president, and some of the officials who were involved have spoken to Smith’s investigators.
