In a statement published on Wednesday, Berliner expressed his respect for the integrity of his colleagues and his desire for NPR to thrive. However, he stated that he could not continue working in a newsroom where he felt disparaged by the new CEO, Katherine Maher, whose past social media posts have gone viral for their far-left views.

Berliner had previously criticized NPR's coverage of various topics, including Russiagate, the COVID lab leak theory, Hunter Biden's scandalous laptop, and the organization's embrace of the theory of systemic racism. He also accused NPR of downplaying antisemitism after an incident on Oct. 7. Additionally, Berliner pointed out a significant disparity between Democrats and Republicans in the NPR newsroom in Washington, D.C. based on registration records in 2021. He claimed that some staffers were actively working against the presidency of Donald Trump, despite having voted against him himself.

Berliner's piece in the Free Press garnered backlash from his colleagues, with some expressing their unwillingness to work with him any longer. As a result, he was suspended for five days without pay, with NPR issuing a "final warning" stating that further violations of their policy regarding outside news organizations would lead to termination. Instead, Berliner chose to resign.

NPR figures, including "Morning Edition" host Steve Inskeep, publicly opposed Berliner's conclusions. However, Berliner's work over the years had received several prestigious accolades, including a Peabody Award, a Loeb Award, an Edward R. Murrow Award, and a Society of Professional Journalists New America Award, according to NPR's website.

When asked for comment on Berliner's resignation, an NPR spokesperson declined to provide a statement, citing a policy against commenting on individual personnel matters. Last week, the spokesperson directed Fox News Digital to a memo from editor-in-chief Edith Chapin, where she expressed strong disagreement with Berliner's assessment of NPR's journalism and integrity.

NPR has also continued to support CEO Katherine Maher, despite her previous support for Hillary Clinton and Joe Biden's presidential campaigns, as well as her public criticism of Donald Trump on social media. In response to the recently surfaced posts, an NPR spokesperson called the criticism a "bad faith attack."

As Berliner's resignation unfolds, the controversy surrounding perceived liberal bias at NPR continues to be a topic of discussion within the media landscape.
