  We discuss the impact of additional two-body decays of the right-handed
neutrino into a light charged Higgs state on the dilepton plus dijet cross
sections from resonant $W'$ production. We consider in particular a
supersymmetric left-right symmetric model which predicts such a light charged
Higgs boson. We demonstrate that the $eejj$ excess as measured by CMS can be
explained best if the $W'$ also has decay modes into Higgsino-like charginos
and neutralinos with masses of a few hundred GeV. Provided that this excess is
confirmed, the model predicts also one right-handed neutrino with a mass below
200 GeV as well as a doubly charged Higgs boson which should be discovered at
the LHC in the near future.
