Influential White House staff secretary Rob Porter resigned Wednesday in the wake of reports he physically abused two ex-wives, reports that he maintains are "vile" and "simply false." The claims come via Colbie Holderness (who married Porter in 2003) and Jennifer Willoughby (who married him in 2009). The Washington Post reports White House staffers knew vaguely of the situation as of late 2017, but only heard the alleged details when contacted Tuesday by a reporter from the Daily Mail, which first reported the women's story. But Holderness and Willoughby say they did tell the FBI what happened in January 2017. "I thought by sharing my story with the FBI he wouldn’t be put in that post," Holderness says, explaining that she voiced concerns he could be blackmailed because of the number of people who knew about her situation.
