Abstract: We describe a search for anomalous production of events with two leptons ($e$ or $\mu$) of the same electric charge in \ppbar collisions at a center-of-mass energy of 1.96 TeV. Many extensions to the standard model predict the production of two leptons of the same electric charge. This search has a significant increase in sensitivity compared to earlier searches. Using a data sample corresponding to 1 \invfb of integrated luminosity recorded by the CDF II detector, we observe no significant excess in an inclusive selection (expect $33.2\pm4.7$ events, observe 44) or in a SUSY-optimized selection (expect $7.8\pm1.1$ events, observe 13.)
