There may have been 2 spies.
Sounds like Mifsud was not a CF member. Also sounds like he would not be a likely candidate for an FBI spy. He is neck deep in the collusion of a coup.
Alexander Downer was also very instrumental in getting the ball rolling on U1. He was a member of the CF Board and got the AUS govt to donate billions to the foundation. That his name comes into the picture on this tells you he had big plans if she had won, so was very motivated to make sure Potus didn't.
