Harold Hamm

The US administration-in-waiting nominated by President-elect Donald Trump is a circle of multimillionaire businessmen and women the public may view as a cabinet whose wealth is unprecedented in US history.

Sue Ann Arnall, the ex-wife of Oklahoma oil magnate Harold Hamm, has deposited a handwritten $975 million divorce cheque, Hamm's lawyer said on Thursday, in a move that may end an epic divorce battle over a fortune worth billions.

The cheque wasn't in the mail. It was hand-delivered to her lawyers, but Sue Ann Arnall, the ex-wife of an American oil mogul, sent it right back on Monday.

Just how much of Harold Hamm's fortune was amassed through his skill and hard work?
