It stated very specifically in my pledge manual that we have no official, formal, or recognized affiliations with any fraternity, although I am certain Robert E. Lee, whom I believe to be a KA (ETA: but apparently is just a "spiritual founder", whatever that is) is an honorary member of Phi Mu. All things aside I do not recognize nor have I been taught to recognize any fraternity as having a special relationship with Phi Mu on a national level and if I did (which I DO NOT) it would be to Sigma Nu as our creeds are essentially the same.

Robert E Lee was never a KA he's only our SPIRITUAL founder , but thanks for your answer
