They call themselves the “Fox ‘News’ Channel.” It’s a conservative-leaning cable network that has purported to present the “news” in a “fair and balanced” manner.

Well, check out the caption under the TV image that flashed on the Fox “News” Channel. It parrots the epithet that Donald J. Trump has used to disparage U.S. Sen. Elizabeth Warren, the Massachusetts Democrat who has just announced the formation of an exploratory committee to help her decide to run for president in 2020.

The “Pocahontas” label, of course, is Trump’s way of ridiculing Warren’s contention that she has some Native American blood in her background. The president has decided Warren’s claim is without merit, so he has hung that label on her.

Fox has glommed onto it as well.

Is that how one might define a mainstream “news” network’s “fair and balanced” coverage of a still-developing presidential campaign?

Imagine what political conservatives might think — and say — if CNN or MSNBC broadcast an image of Donald Trump with the caption that read “Cadet Bone Spur,” or “Liar in Chief,” or, well . . . you get the idea.

The Fox “News” Channel simply demonstrates yet again that it is neither “fair” or “balanced.” It serves instead as a de facto presidential mouthpiece.

Disgraceful.
