Michelle Fields, a reporter for the archconservative news outlet Breitbart, was asking Donald Trump a question this past Tuesday when a man, identified by at least one eyewitness as Trump campaign manager Corey Lewandowski, grabbed her arm hard enough to leave a bruise and pulled her forcefully away from the candidate. Since then, pro-Trump reporters, flacks and even Trump himself have attempted to discredit Fields, but the most egregious discrediting efforts have come from Breitbart itself—a cozy, pro-Trump outlet that began gaslighting its own employee almost immediately after the incident, and has not let up since.
