The DO Collaboration has published three measurements of the like-sign dimuon charge asymmetry in p-pbar collisions at the Fermilab Tevatron collider. The result is significantly different from the standard model prediction. We present the final measurement of this CP-violating asymmetry, using the full 10 fb^-1 of data collected during Run II, and discuss its possible interpretations.
