In a Politico article detailing how President-elect Donald Trump’s “horde of enforcers” -- Breitbart.com listed prominently among them -- are scaring Republican lawmakers away from criticizing him, a Breitbart editor said Republicans are right to fear the right-wing website, which was previously run by Trump senior counselor Stephen Bannon. This admission from Breitbart that the outlet plans to support Trump, rather than objectively cover his incoming administration, further demonstrates that the website is not editorially independent enough to warrant permanent Capitol Hill press credentials.

Breitbart applied for permanent Capitol Hill press credentials in November. Media Matters has objected to the request, urging members of the Standing Committee of the Senate Press Gallery in an open letter to reject the request based on Breitbart’s disqualifying inability to demonstrate editorial independence from the Trump team as required by the committee's rules. Breitbart fails this standard in several ways, as several former members of the committee have acknowledged. In a December 21 Politico report headlined “Trump posse browbeats Hill Republicans,” Breitbart further demonstrates why the site must be disqualified from obtaining a permanent press pass by admitting that it will go after Trump’s Republican critics.

From the Politico article (emphasis added):

In early December, Rep. Bill Flores made what seemed like an obvious observation to a roomful of conservatives at a conference in Washington. Some of Donald Trump’s proposals, the Texas Republican cautioned, “are not going to line up very well with our conservative policies," though he quickly added that there was plenty the incoming president and GOP Congress could accomplish together. Little did Flores realize the hell that would soon rain down from Trump's throng of enforcers.

Breitbart seized on Flores' remarks a few days later, calling them proof that House Republicans planned to “isolate and block President Donald Trump’s populist campaign promises.”

It’s little wonder that Capitol Hill Republicans have papered over their not-insignificant policy differences with Trump, shying away from any statement about the president-elect that might possibly be construed as critical. They’re terrified of arousing the ire of their tempestuous new leader — or being labeled a turncoat by his army of followers.

It's a novel form of party message discipline that stems from Trump but doesn't necessarily require the president-elect to speak or tweet himself. Plenty of others are willing to do it for him. Since the election, numerous congressional Republicans have refused to publicly weigh in on any Trump proposal at odds with Republican orthodoxy, from his border wall to his massive infrastructure package. The most common reason, stated repeatedly but always privately: They're afraid of being attacked by Breitbart or other big-name Trump supporters. “Nobody wants to go first,” said Rep. Mark Sanford (R-S.C.), who received nasty phone calls, letters and tweets after he penned an August op-ed in The New York Times, calling on Trump to release his tax returns. “People are naturally reticent to be the first out of the block for fear of Sean Hannity, for fear of Breitbart, for fear of local folks.”

An editor at Breitbart, formerly run by senior Trump adviser Steve Bannon, said that fear is well-founded.

“If any politician in either party veers from what the voters clearly voted for in a landslide election … we stand at the ready to call them out on it and hold them accountable,” the person said.
