The production of chargino-neutralino (χ ± 1 χ 0 2 ) pairs and their subsequent leptonic decays is one of the most promising supersymmetry (SUSY) signatures at the Tevatron proton-antiproton collider. We present here the most recent results on the search for the three-lepton and missing transverse energy SUSY signature using data collected with the CDF and DØ detectors. At CDF, charginoneutralino pairs are also searched for using events with a Z (decaying to e + e − ), two or more jets from a W

... decay, and large missing transverse energy. The presented results, based on data corresponding to 1.0-3.2 fb −1 of integrated luminosity, are interpreted in the minimal supergravity scenario.
