Starting with a microscopic model for itinerant electrons with strong local repulsion and a weak attraction of longer range we derived coupled self-consistency equations for coexisting itinerant magnetism and superconductivity. Solutions for strong ferromagnetism and nonunitary triplet superconductivity with orbital angular momentum l=1 are presented.
