The ATLAS collaboration has recently reported a mild hint for a new resonance at around 2 TeV decaying to WW, WZ, and/or ZZ pairs. Intriguingly, similar though less significant excesses are also seen in other final states, for instance H+W and dijets. In this talk, we report results of a model-independent fit to all relevant ATLAS and CMS searches in this context. We discuss possible theoretical interpretations of the tentative signals, focusing in particular on left-right symmetric models with gauge group SU(2)_L x SU(2)_R x U(1), where the right-handed partner of the W can explain the excesses. We also comment on possible connections of such a scenario to the dark matter in the Universe.
