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.
