Advice for a Rushee's Mom

[Mizzou'84]

My daughter and her best friend are rushing at the University of Missouri in the fall. I was an alumnae at Mizzou but unfortunately never rushed a sorority. My daughter and her best friend want to do it this year and I am encouraging her to do it. She is white (irish descent) and her friend is black. They are both rushing PHA but my daughter's friend does not want to do it because she heard that sororities never accept black girls at mizzou. I do not know any of this because I was never in a sorority but i tried to do some research online which lead me to a thread on this website (didn't even know such a thing existed). My daughter's friend is like a second daughter to me so i have been researching to see if this is true but have come up empty. Can anyone help me with this information so I can talk her into rushing? She payed almost 200 dollars to rush and I would hate for her to lose it because she decided not to do it anymore. She has no recommendations (which she did not get because she was indecisive with rushing).
Should I stop trying or should I talk to her mother(who is one of my best friends) about it?
