From mode-coupling theory, we obtain the complete long-time behavior of kinetic, potential, and cross terms of the Green-Kubo integrands for the transport coefficients in a classical electron gas. The results for the kinetic parts are in agreement with those derived recently with use of kinetic theory. The differences between the long-time tails in the electron gas and those in neutral fluids are discussed in detail. The theory suggests that the frequency-dependent heat conductivity diverges as the plasma frequency is approached.
