Yeah, it's editorializing. If they want to clarify something, it's easy to alter the format to allow for that in a way that doesn't make the presenter the arbiter of fact versus fiction. However, the idea that, again, a "straight" news program (one or two people reading news stories and showing video clips) should have the presenter(s) commenting on the stories they're presenting is silly when, again, there are plenty of formats and avenues for such commentary.
"Here's what Presidential Candidate Donald Trump said today in a speech given in Dallas, Texas."

"In Hoboken, New Jersey, Hillary Clinton gave a speech on health care."
<play video>
"In other news..."
There is nothing wrong with presenting the news like that. Inserting anything else is for another kind of show.
