President Obama Wednesday told Republican presidential nominee Donald Trump to quit "whining" about a possible rigged election. "I'd advise Mr. Trump to stop whining and go try to make his case to get votes," Obama said. Obama would also tell Trump that he "doesn't have what it takes" to be president while talking to reporters at the White House. The real estate mogul is currently in a fight to improve his image nationally as polls show him at least a few percentage points behind Hillary Clinton.
