Washington: US President Barack Obama urged Republican presidential nominee Donald Trump to "stop whining" and rejected his claims of the presidential elections being rigged, media reports said.
"I have never seen any presidential candidate trying to discredit the elections and the election process before votes have even taken place. It's unprecedented," CNBC news quoted Obama as saying at a White House press conference on Tuesday.
"I'd invite Mr. Trump to stop whining, and go try to make his case to get votes," he added. Trump clashed with Democratic presidential nominee Hillary Clinton and his own party on whether the upcoming election was rigged.
"The election is absolutely being rigged by the dishonest and distorted media pushing Crooked Hillary - but also at many polling places - SAD," Trump tweeted on October 16. Poll numbers in favour of Trump drastically fall after the first presidential debate on September 26.
This was followed by the release of a 2005 tape on October 8, in which Trump bragged about sexually aggressive behaviour toward women. After this, several women have accused the Republican candidate of sexual misconduct.
Currently, Clinton leads Trump by 12 percentage points according to a poll conducted by The Monmouth University. Trump and Clinton will face off in the third and final presidential debate at the University of Nevada, Las Vegas, on October 20.
