Hillary Clinton has decried the rise of fake news as an "epidemic" in her first speech since losing the US presidential election last month.
Mrs Clinton addressed fake news during a speech for retiring Nevada senator Harry Reid at the Capitol in Washington.
The Democrat warned that "it's now clear that so-called fake news can have real-world consequences", an apparent reference to an incident involving a gunman who fired multiple shots inside a Washington pizza shop that has become the target of a fake conspiracy story.
Amusing to see a mainstream media that facilitated austerity & gave Trump and Farage unlimited airtime blame the rise of fascism on blogging

Mrs Clinton said the issue "is not about politics or partisanship".
She added: "Lives are at risk. Lives of ordinary people just trying to go about their days to do their jobs, contribute to their communities."
