WH press sec, reporters spar over 'fake news'

White House press secretary Sarah Huckabee Sanders sparred with reporters during her Dec 11 briefing over errors made by media outlets in reports on President Donald Trump. Sanders disputed the notion that mistakes made by news outlets were “honest mistakes” during a heated exchange with CNN’s Jim Acosta.  "You cannot say it's an honest mistake when you're purposely putting out information you know is false," Sanders said. Sanders and Acosta talked over one another during the exchange. “I’m not finished,” she responded when reporter Brian Karem tried to cut in. The exchange with Acosta comes amid escalating tensions between the White House and CNN.
