Breitbart's Michelle Fields, Ben Shapiro resign over Trump incident

Breitbart reporter Michelle Fields has resigned from the conservative news site over its response to her alleged assault by Donald Trump's campaign manager.

Her colleague Ben Shapiro also resigned from Breitbart, saying the site should be "ashamed" of "their treatment" of Fields, whose allegations of assault came amid escalating violence in and around Trump campaign events.

Fields accused Trump campaign manager Corey Lewandowski of grabbing her arm so hard she bruised as she attempted to question the candidate at an event. She wrote an account of the incident, as did a Washington Post reporter who said he witnessed it. Politico also published an audio transcript that purportedly captures the interaction and moments immediately afterward.

The Trump campaign fought back hard against the allegations. Lewandowski called Fields "delusional" and an "attention seeker," while Trump accused the reporter of having "made up" the incident. Fields, meanwhile, filed a police report.

In the immediate aftermath, another Breitbart reporter appeared to question Fields' allegations on Twitter. That reporter was suspended -- and the news site's chief executive issued a statement backing Fields and calling on Lewandowski to apologize.

However, the site then published images questioning whether the Washington Post's Ben Terris misidentified Lewandowski as the person who may have physically assaulted Fields. Breitbart later published a piece purporting to show text messages from Lewandowski which it said "prove" he didn't assault Fields.

That appeared to be the final straw for Fields, who informed management of her resignation on Sunday night.

"I do not believe Breitbart News has adequately stood by me during the events of the past week and because of that I believe it is now best for us to part ways,"she said in a statement issued to BuzzFeed.

Her colleague Shapiro went further, saying Breitbart should be "ashamed" of themselves for abandoning and undercutting Fields in order to protect a "bully" -- Trump -- and his "bully campaign manager."

"Both Lewandowski and Trump maligned Michelle in the most repulsive fashion. 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," Shapiro said in a statement issued to BuzzFeed.

He said the story suggesting Fields and Terris had misidentified Lewandowski -- a "poorly-evidenced conspiracy theory" -- was the "ultimate indignity."

"This is disgusting," Shapiro said. "No news outlet would stand for it."

Breitbart News has not commented on the resignations.

The Fields incident came a week after a Time magazine photographer was thrown to the floor by a Secret Service agent at another Trump rally and amid escalating concerns over the rhetoric used by the Republican frontrunner.

Trump has come under mounting criticism -- from Democrats and from Republican rivals -- for failing to fully denounce violent incidents at his events and for creating a climate where such incidents can persist.

Those issues were amplified in recent days after video emerged of a man at a Trump rally sucker-punching a protester leaving an event in North Carolina and fights broke out at a cancelled event in Chicago.

Trump himself has said he would like to punch a protester in the face and see another taken out on a stretcher.
