Trump and his surrogates have in recent days claimed that the US election system is "rigged," coming after the candidate's two lackluster debate performances and a drop in poll numbers nationally and in key swing states. He even mentions St. Louis as part of the problem.
"We have voters all over the country, where they're not even citizens; and they're voting. There are certain cities, I won't name them right now. But, Philadelphia is one that is mentioned. Mitt Romney got no votes, McCain got no votes; no votes," said Republican presidential candidate Donald Trump. "You look at what is going on in Chicago. You look at what is going on in St. Louis, and many other cities. There is tremendous voter fraud. How the Republican leadership does not see that is beyond me."
President Barack Obama sharply disputed Donald Trump's claim that the US election system is rigged, saying the Republican presidential nominee should "stop whining."
"He started whining before the game's even over," Obama said Tuesday during a news conference in the White House Rose Garden, adding that Trump's claim is "not based on facts."
Trump's preemptive warnings of a "rigged election" are entirely unprecedented in modern American political history, Obama said.
"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," Obama said alongside Italian Prime Minister Matteo Renzi.
He cast Trump's warnings as a debunked myth, saying no evidence of widespread voter fraud exists.
"If whenever things are going badly for you and you lose, you start blaming somebody else, then you don't have what it takes to be in this job," Obama said.
