NPR has formally punished Uri Berliner, the senior editor who publicly argued a week ago that the network had "lost America's trust" by approaching news stories with a rigidly progressive mindset.

Berliner's five-day suspension without pay, which began last Friday, has not been previously reported.

National Public Radio has suspended an editor who has repeatedly criticized the outlet in recent days, alleging a left-leaning bias that he says is hurting the organization’s journalism.

Uri Berliner, a senior editor who has worked at NPR for more than 20 years, was suspended last week by the company for five days without pay, NPR’s media reporter David Folkenflik reported Tuesday.

NPR has suspended Uri Berliner, the senior editor who published a bombshell essay a week ago that claimed that the publicly funded outlet has “lost America’s trust” by approaching news stories with a left-wing bias.

NPR media writer David Folkenflik revealed on Tuesday that Berliner beginning on Friday was suspended for five days without pay. Folkenflik, who reviewed a copy of the letter from NPR brass, said the company told the editor he had failed to secure its approval for outside work for other news outlets — a requirement for NPR journalists.
