United States President Barack Obama on Tuesday told the Democratic presidential nominee Donald Trump that there is no evidence over Trump's repeated claims that 2016 US election is rigged. The US President also said that Trump should "stop whining" and make his case to get votes.

Obama made the statement at a joint news conference at the White House Rose Garden following his meeting with the Italian Prime Minister Matteo Renzi. During the conference, the President was asked about Trump's claims that there were efforts in US cities to "rig the election at the polling place."

Responding to the reporters' questions, Obama said, "I'd invite Mr Trump to stop whining and go try to make his case to get votes."

Donald Trump has repeatedly claimed over his campaigning months that there are possibilities that illegal activities in the 2016 elections could lower his chances of winning the US presidential seat. Trump has even asked his supporters to stay vigilant and turn up at the polling locations on November 8.

The Republican nominee has intensified his claims of rigged elections at his campaigns ever since his public opinion polls have begun falling.

Obama also said that Trump's claims of the elections being rigged is "unprecedented. It happens to be based on no facts."

"By the way, [it] doesn't really show the kind of leadership and toughness that you want out of a president, if you start whining before the game's even over...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 added.

The US President also made a statement on Trump's admiring remarks for the Russian President Vladimir Putin.

"Mr Trump's continued flattery of Mr Putin and the degree to which he appears to model much of his policies and approach to politics on Mr Putin is unprecedented," he said.
