New appointment to the Justice Department's Office of Professional Responsibility… can't find news ANYWHERE of the person being replaced, other than info about her appointment by Eric Holder. Her name is Robin Ashton. The press release only says she is leaving after a decade of service. Release dated 10/2/18 but on Justice's OPR website, Mr. Corey Amundson was appointed sometime in September.

So I don't know if you can count that as a notable resignation or what because I can't find shit on her leaving.
