Michelle Obama an AKA?????

Sunday night (July 13th), it was announced at the Alpha Kappa Alpha Sorority, Inc. Boule (National Convention) that Michelle Obama will be inducted as an honorary member of Alpha Kappa Alpha Sorority, Inc. Sources on the scene at the National convention tell me the ceremony is set to take place this week in Washington, DC during the Sorority’s National Convention festivities.
I won’t hold it against her since I’m sure it was strictly a timing convenience for which Sorority she would be inducted into since this is the centennial anniversary of the Sorority and the convention is happening this week in DC.
Congrats to Mrs. Obama and congrats to the ladies of Alpha Kappa Alpha Sorority, Inc. But I do have one pressing question; whats the point of having honorary members?
