Well that actual quote was "find the fraud", which given his personal very distant relationship with honesty, was simply a differently worded directive to find something that doesn't exist.Trump 'believed' that there were 100s of thousands of votes that had not been counted. And he was saying "i don't need you to find all of them, just enough for me to win the electoral votes."
I can't find on Google whether the election officials had already asserted there was none.
