Let f:X\to Y be a torsor for a semisimple group G with $Y$ a smooth and geometrically irreducible variety over an arbitrary field. We relate the etale motivic cohomology of weight two for X, Y and G. We also compute the etale motivic cohomology groups of degree at most 4 for the classifying space of G.
