Breitbart senior editor-at-large Joel Pollak tweeted "#WAR" after White House chief strategist Steve Bannon left President Donald Trump's administration Friday.

Before joining the administration, Bannon was chairman of Breitbart News, a conservative media outlet. Pollak told CNBC on Friday that "war" has been Breitbart's motto from the beginning. The phrase means Breitbart will go to war, "rhetorically speaking," to "defend Americans" from the mainstream media, Hollywood, Democrats and mainstream Republicans.

"I'm not launching the bombers by tweeting #WAR," Pollak said on "Power Lunch."

He said Breitbart will be "happy warriors." It will have "fun" as it stands up for the principals it supports.

"Yet it is going to be a war because the mainstream media and Hollywood do not want America to function the way it was designed to function," Pollak said. "They believe the American Constitution was conceived in original sin."

Bannon reportedly is planning on "going to war" with Trump administration officials. Pollak, however, said Bannon's departure will not change Breitbart's coverage.

"We remain as we've always been: the outlet that represents the movement and the ideas that brought Trump to office," Pollak said. "Whether he remains onboard with that agenda is now an open question with Steve Bannon's departure from the White House."

Breitbart has at times been critical of Gary Cohn, director of the National Economic Council. It criticized the former Goldman Sachs banker for partying in the Hamptons earlier this month and "privately undermining the president's message" after violence erupted at a white nationalist rally in Charlottesville, Virginia, this week.

Pollak was mum when asked about Cohn. Pollak said he wished Cohn's tax reform plans the best, but he did not know much about him except that he is a registered Democrat.

"I think there's a fear among conservatives that with Steve Bannon gone, essentially the Trump administration could become in all but name a Democratic administration," Pollak said.



"We'll see what happens, we'll see if that continues, we'll see if Trump can pull back a team of rivals that can work together to fulfill the agenda he was elected on and that's all I can really say."
