More than 300 newspapers -- including The New York Times, The Boston Globe and the Miami Herald -- are banding together and running editorials pushing back on President Trump and condemning his description of the press as the "enemy of the people."

Former White House Press Secretary Ari Fleischer believes this is a "meaningless exercise" because it just reinforces that much of the mainstream media is pack journalism, with reporters and editorial boards who all think alike.

On "America's Newsroom," Fleischer said he agreed with a Politico piece that argued the newspapers "just played right into Trump's hands."

"It's the groupthink, it's the liberal-think, it's how they all go the same way," Fleischer said.

He added that if editorials actually moved the needle, then Hillary Clinton would be president, because the press was overwhelmingly supportive of her candidacy over Trump's.

"It's just a group of liberal, biased reporters sharing the same thoughts at the same time," Fleischer said.

He acknowledged that he would not go as far as Trump does with his press bashing, but it's been clear for decades that the media has an anti-conservative bias.

"The press, the mainstream media, has been biased for far, far too long," Fleischer said. "There's an issue with bias where they love to go after Republicans and they omit going after Democrats."
