DoodleDawg :" Unfortunately in terms of invalidating the election he doesn't have the authority to do so. "

Actually, therein lies the conundrum !
Nobody has the authority, because it is not addressed in the Constitution !
The Founding Fathers would never have believed that a nation-wide fraud could occur,
so they never delegated that authority to anyone, or any agency.

Each state validates their votes in the legislators. They choose the electors to vote in the EC. The legislators can refuse to validate the election results and give all the electors to Trump.
