Sarah Sanders: 'Laughable' for Obama to Try to Take Credit for Economy

White House Press Secretary Sarah Sanders battled CNN reporter Jim Acosta, accusing the mainstream media of "purposefully" putting out false information. 

As he began a question, Acosta told Sanders at Monday's press briefing that journalists make "honest mistakes" and that doesn't mean it's "fake news."

Sanders started to answer but Acosta and another reported interjected.

"I'm sorry. I'm not finished!" she countered.

"There's a very big difference between making honest mistakes and purposefully misleading the American people, something that happens regularly," she shot back.  

Acosta asked for an example of a story that was "intentionally false" and meant to mislead Americans.  

Sanders called out the false report by ABC News' Brian Ross on former National Security Adviser Michael Flynn, which earned Ross a four-week suspension

She called it "very telling" that Ross was suspended. Acosta kept pushing Sanders to let him ask his original question about allegations of sexual misconduct against President Trump, but she refused.

On Friday, CNN corrected a scoop which initially claimed WikiLeaks provided access to stolen emails to Donald Trump Jr. on Sept. 4, 2016, before they were public. The report was later corrected to say that the email was sent Sept. 14, after the hacked documents were released by WikiLeaks.

The report drew ire from President Trump and his oldest son.

Reporting after the briefing, Fox News chief White House correspondent John Roberts said he has not seen Sanders get as "worked up" as she did in the argument today with Acosta. 

Roberts said he sees a "race" playing out among news outlets to be first to report damaging information about the Trump White House.

Watch the tense exchange above.
