Former NPR business editor Uri Berliner is fed-up with his old employer.

Calling bias in a bombshell opinion piece Wednesday, he says it can't be trusted.

He worked there from 1999 until his resignation in April 2024, at which time he penned a separate piece titled, I've Been at NPR for 25 Years. Here's How We Lost America's Trust.

He was out of a job a week later.

In an editorial for the same publication he slammed NPR in the first place, the 69-year-old said the broadcaster's claims about being impartial were all but thrown out the window - thanks to perceived propaganda-peddling during the pandemic.

His comments came as NPR's CEO and President Katherine Maher is set to appear in front of the House Oversight Subcommittee chaired by Marjorie Taylor Greene on Wednesday, facing the prospect of a loss in federal funding. 

PBS's CEO and President Paula Kerger will be there as well. Both women maintain their organizations are merely working to create a more informed public.

Others claim they consistently skew reporting to favor liberal opinions - Berliner included.

'The broadcaster's claims about considering all things and its mission of creating "a more informed public" were demolished when it unquestioningly repeated the talking points of the Biden administration and the public health establishment during Covid,' he wrote in The Free Press.

He went on to explain some of the circumstances of his ouster, which he has already blamed on Maher's negative response to his outside essay.

He described how for 'most of the 25 years' he worked at NPR, he felt 'honored' to call himself a staffer, but soon became troubled by instances of bias that he said stemmed from a lack of diversity amongst other NPR journalists. 

'Though I tried flagging my concerns to my bosses, it fell on deaf ears,' he wrote.

'And so, nearly a year ago, I wrote my whistleblowing piece in these pages,' he continued, recalling how he had argued 'NPR had morphed from a liberal but open-minded news organization driven by curiosity into a conduit for progressive ideology.'

He brought up how in the months since, after his essay went viral on sites like X, NPR said last May it was introducing a new 24/7 vetting process 'to ensure that all coverage receives final editorial review,' the outlet said at the time.

But Berliner concluded that so-called 'backstop' was all talk  - bringing up reports that emerged from NPR's website when Hezbollah leader Hassan Nasrallah was assassinated last September as proof.
