Former Washington, D.C., Councilman Jack Evans is launching a comeback bid for the district council six years after his resignation from the governing body.

Evans is running for the chairman spot in a direct challenge to current Chairman Phil Mendelson. Evans and Mendelson, both Democrats, were colleagues on the D.C. Council before Mendelson voted unanimously with the council to recommend Evans’s expulsion due to numerous ethical violations. On Tuesday, six years after he resigned over the ethics concerns related to his outside employment, Evans announced his bid to return to the council.
