Glenn Greenwald, a Pulitzer Prize-winning liberal journalist, said Monday night that a desire to prove President Donald Trump colluded with Russia during the 2016 campaign is leading journalists to multiple embarrassing mistakes.

Greenwald told host Laura Ingraham on the Fox News program “The Ingraham Angle” that Friday’s false CNN report about WikiLeaks and the Trump campaign is just the latest example.

“These mistakes stop looking like mistakes when they always go in the same direction and bolster the same political agenda, and I think you’re seeing that around most media outlets,” said Greenwald.

CNN cited confidential sources in reporting that emails sent to the Trump campaign and the president’s son, Donald Trump Jr., contained information hacked before the public knew about it. CNN later admitted it had gotten the date of the emails wrong, but other networks had run with it.

Greenwald asked how CNN, along with CBS and MSNBC — which claimed they had confirmed CNN’s report — could all have gotten the story so wrong in the same way.

“They all claimed that multiple sources told them that this email sent to Don Jr. was dated before the WikiLeaks publications became public,” he said. “How did multiple sources all get the same date wrong when talking to multiple media organizations?”

None of those media organizations have since been transparent about how the error occurred, Greenwald said.

“It seems like it was a deliberate attempt to mislead, in which case they have an obligation to say which members of Congress — probably Democrats on the Intelligence Committee — were the ones that gave them that false information,” he said. “But if it wasn’t deliberate, they have the obligation to say how it happened.”

Greenwald pointed to “a long line now of stories about Trump and Russia that major media outlets have trumpeted in a very flamboyant way, only for those stories to completely fall apart upon minimal scrutiny … So it’s not just one mistake. It’s a huge series of them, always toward the same outcome and the same agenda.”

CNN’s defenders have characterized the mistakes as good-faith efforts to uncover the truth. But Greenwald suggested ideological bias has played an outsized role.

“If people were just making mistakes journalistically because they were rushing or because human beings are fallible, as we all are, you would expect roughly 50 percent of the mistakes to go in one direction and 50 percent of the mistakes to go in the other direction,” he said. “And what you’re seeing in this story is the exact opposite.”

Greenwald added that virtually 100 percent of the mistakes “are designed to undermine and subvert Donald Trump and to bolster the Russia-Trump story, just like all of Fox’s mistakes are in the opposite direction.”

Polling shows large majorities of Americans have steadily lost faith in journalists over several decades. The reason, said Greenwald, is that media have become a “balkanized” series of ideological silos where journalists talk only to small subsets of the population.

“That is what, I think, is ruining journalism,” Greenwald told Ingraham.
