US election 2016: Stop whining, Obama tells Donald Trumppublished at 09:05 British Summer Time 19 October 2016
US President Barack Obama has told Donald Trump to "stop whining" as he rejected his claim that next month's White House election will be rigged.
He said Mr Trump's attempt to discredit a poll before it has even taken place was "unprecedented" for a US presidential candidate.
Also "unprecedented", said Mr Obama, was the Republican candidate's "flattery" of Russia's president.
Mr Trump is facing sinking poll numbers and accusations of sexual assault.
