Using the Boltzmann equation for electrons in metals, we show that the optical phonons soften and have a dispersion due to screening in agreement with the results reported recently [M. Reizer, Phys. Rev. B \bf 61, 40 (2000)]. Additional phonon damping and frequency shift arise when the electron--phonon interaction is properly included.
