to report known facts without commentary or bias. That's called reporting. Sometimes there is a need to connect new facts with other known facts. That provides context.

Each may ALSO provide commentary that has the biases of the commentators. That's the stuff on the editorial pages or when CNN trots out a panel of people to discuss something.

Here's some interesting quotes - I will link the source:
"Why is freedom of the press important?
Freedom of the press is important because it plays a vital role in informing citizens about public affairs and monitoring the actions of government at all levels. While the media may be unpopular —43 percent of Americans say the media supports democracy “very poorly” or “poorly,” a Knight Foundation/Gallup report found — this role should not be forgotten.
To protect our rights, we must understand our rights. ….
The founding fathers valued a free press.
Media-bashing is as old as the nation itself. George Washington once referred testily to the “infamous scribblers” who covered his administration. But our revolutionary forefathers knew that when the press examines the actions of government, the nation benefits. News organizations expose corruption and cover-ups, deceptions and deceits, illegal actions and unethical behavior—and they hold our leaders and our institutions accountable, whether it’s a rural county in Kentucky or the state government in Illinois.
Today, reporters face an increasingly hostile environment. Journalists and freelance writers have been forced to hand over cell phones and other devices to border agents for inspection when exiting or entering the United States, the nonprofit Committee to Project Journalists reports. Border agents have also interrogated them about everything from private conversations to their social media posts.
At a local level, journalists were arrested at least 34 times in 2017, according to Reporters Without Borders. Nine journalists were arrested for covering protests in St. Louis, the group reports, and a journalist in North Dakota was arrested for covering a Dakota Access pipeline protest. Reporter Dan Heyman was jailed in West Virginia last year after asking then Health and Human Services Secretary Tom Price a question about healthcare legislation (the charge was willful disruption of state government processes). On a national level, the President has retweeted violent memes against CNN and railed against reporters and news outlets that criticize his administration, even stating that certain media outlets should lose their broadcasting licenses. He has called the press “enemies of the people,” a phrase also used by, yes, Joseph Stalin."
