We present results of a search for anomalous production of events containing a charged lepton (l, either e or {mu}) and a photon ({gamma}), both with high transverse momentum, accompanied by additional signatures X, including missing transverse energy (Ee{sub T}) and additional leptons and photons. We use the same selection criteria as in a previous CDF search but with a substantially larger data set, 305 pb{sup -1}, a pp collision energy of 1.96 TeV, and the CDF II detector. We find 42 l{gamma}Ee{sub T} events versus an expectation of 37.3{+-}5.4 events. We observe 31 ll{gamma}+X events versus an expectation of 23.0{+-}2.7 events. We find no events similar to the run I ee{gamma}{gamma}Ee{sub T} event.
