Chris Wallace from Fox News isn't happy Donald Trump called the media an "enemy of the American people," and on Sunday, he let the president's chief of staff know it.

Talking on Fox News Sunday, the veteran news reporter — himself a former White House correspondent — pushed back against Trump's comments (made on Twitter, of course) to Reince Priebus.

"But you don’t get to tell us what to do, Reince," Wallace said. "You don’t get to tell us what to do any more than Barack Obama did. Barack Obama whined about Fox News all the time, but I got to say, he never said that we were an enemy of the people."

For fuller context, here's a longer clip centered around the conversation about the media.

As if to remove any doubt of where he personally stood on the matter, Preibus appeared on another Sunday news show, CBS' Face The Nation, where he told John Dickerson that people should take Trump's words "seriously."

When Trump calls the media “the enemy,” should we take him seriously?

The whole mess started last week when Trump tangled with the media in that bizarre press conference and sent an equally surreal anti-media survey out to his email list. He followed that up with a tweet that directly attacked several traditional, reputable news outlets as "the enemy of the American people."

What makes Wallace's words noteworthy is that he's the second major Fox News anchor to fight back against the president's attacks on media, even as Trump has often, in the same breath of his attacks, praised the preening softball-question-parade morning show that is Fox & Friends.

Previously, Shep Smith criticized Trump's attacks on CNN and, after this most recent press conference, again went after Trump for what he called "crazy" and "ridiculous" behavior.

Bringing this whole thing full-circle, Wallace appeared on Fox & Friends on Sunday morning before his own show, where he gave a sign of the criticism that was to come in his sparring with Preibus.
