Vertex corrections to the electrical conductivity of electrons scattered either on thermally equilibrated or statically distributed random impurities are calculated. We demonstrate that the sign of the vertex corrections to the Drude conductivity is in both cases negative. Quantum coherence due to elastic back-scatterings always leads to diminution of charge diffusion.
