We present results of a search at CDF in 929{+-}56 pb{sup -1} of pp collisions at 1.96 TeV for the anomalous production of events containing a high-transverse momentum charged lepton (l, either e or {mu}) and photon ({gamma}), accompanied by missing transverse energy (Ee{sub T}), and/or additional leptons and photons, and jets (X). We use the same selection criteria as in a previous CDF Run I search, but with an order-magnitude larger data set, a higher pp collision energy, and the CDF II detector. We find 163 l{gamma}Ee{sub T}+X events, compared to an expectation of 150.6{+-}13.0 events. We observe 74 ll{gamma}+X events, compared to an expectation of 65.1{+-}7.7 events. We find no events similar to the Run I ee{gamma}{gamma}Ee{sub T} event.
