“Andrew’s life mission has been betrayed,” Shapiro wrote. “Indeed, Breitbart News, under the chairmanship of Steve Bannon, has put a stake through the heart of Andrew’s legacy. In my opinion, Steve Bannon is a bully, and has sold out Andrew’s mission in order to back another bully, Donald Trump; he has shaped the company into Trump’s personal Pravda, to the extent that he abandoned and undercut his own reporter, Breitbart News’ Michelle Fields, in order to protect Trump’s bully campaign manager, Corey Lewandowski, who allegedly assaulted Michelle.”…

“Both Lewandowski and Trump maligned Michelle in the most repulsive fashion,” Shapiro wrote in his resignation statement. “Meanwhile, Breitbart News not only stood by and did nothing outside of tepidly asking for an apology, they then attempted to abandon Michelle by silencing staff from tweeting or talking about the issue. Finally, in the ultimate indignity, they undermined Michelle completely by running a poorly-evidenced conspiracy theory as their lead story in which Michelle and Terris had somehow misidentified Lewandowski.”

The exodus, which began with the company’s spokesman Kurt Bardella, is unlikely to end with Fields and Shapiro. Three sources say multiple staffers are searching for a way out of the company — with several actively circulating résumés, according to two sources — and more resignations could follow in the coming days and weeks. The company is known for having editorial employees sign unusually strict contracts, at least some of which include non-compete clauses that could make it difficult to leave Breitbart for another news outlet.
