UPDATE (4:56 p.m.): D.C. Fire and EMS spokesperson Pete Piringer now states that Rubin has not submitted his resignation paperwork. According to a message left on a media information line, Piringer acknowledged the email which led to the reports of Rubin’s resignation, but said Rubin “has not submitted a resignation, [nor] has he been asked to.” D.C. Fire and EMS chief Dennis Rubin — who was last seen literally packing up his office in preparation of being let go from his post — announced his resignation via email this afternoon, but only after spending two sentences focusing on the fact that his contact information was changing. Unlike Michelle Rhee, Rubin will see out his entire term, and apparently go into consulting after Gray is (presumptively) sworn in as Mayor on January 2. Rubin called his four years in charge of the District’s Fire and EMS a “great opportunity” which he leaves “without regret.”
