This just hours after President Obama scolded Trump to "stop whining" at a White House news conference, joining the pantheon of people advising the GOP nominee to knock off the pity party in advance of tomorrow's final presidential debate and the November 8 election.

"I have never seen, in my lifetime or in modern political history, any presidential candidate trying to discredit the elections and the election process before votes have even taken place. It's unprecedented; and it happens to be based on no facts," Obama said of Trump's claim the election is rigged against him, during a joint newser with Italian Prime Minister Matteo Renzi.

"You start whining before the game's even over? If, whenever things are going badly for you...you start blaming somebody else, then you don't have what it takes to be in this job," the sitting president said, baiting Trump from the Rose Garden.

"I'd advise Mr. Trump to stop whining and go make his case to get votes."

The addition of Obama's half brother, reported by CNN this evening, is Trump's biggest debate stunt to date.

At the most recent debate, Trump tried to have several women who had previously claimed to have been attacked by Bill and/or Hillary Clinton as his guests, but he was thwarted by the debate commission. Ever the showman, Trump instead held a hastily arranged news conference immediately before the debate at which he was flanked by the women. Trump's children and wife took their place in the front row during the debate.
