Description:Recently Bill Maher sat down with Jay Leno and stated that he'd give Donald Trump 5 million dollars if Trump would prove he wasn't related to an orangutang. Trump threw down and produced a copy of his birth certificate, and is now calling out Maher to give up the money he promised (so Trump can donate it to charity). Maher has been mum on the issue, and now Trump is calling foul and threatening to sue the comedian.(1:37)
