You are conflating simple news reports with their editorial
There is a difference between news and opinion pieces, but news reporting also reflects biases. News editors have discretion on what to report (or not report) and how to report it.
The NY Times took 19 days to run a story on Tara Reade's allegations that Joe Biden sexually assaulted her. Their reasoning was that they wanted to wait until there was enough information for readers to make their own judgment.
I'm OK with that logic, but do they apply it evenly?
E. Jean Carroll first accused Trump of sexual assault on June 21, 2019. The NYT ran the story on June 22nd. Did they apply the same due diligence to both accusations?
Consider this NYT news headline:
Ivanka Trump, Disregarding Federal Guidelines, Travels to N.J. for Passover
and from the NY Post:
Hunter Biden still listed on board of Chinese company he was to resign from
The Times did not report on the Biden story and the Post did not report on the Trump story. It doesn't take much research to realize news outlets are more likely to run stories with a particular slant and not run others.
Bottom line: “News” reporting also contains bias, but is often subtle and not immediately apparent.
