I checked the history, and most mentions of Michelle Obama here at the Hall are from Tex or Cassandra (who has posting privileges she may have forgotten). I think the American tendency to pay attention to the First Lady and families of Presidents is a mistake, probably JFK's fault, that only hurts their ability to carry on with family life during a difficult few years. Best to ignore them and what they do, almost all the time, for the sake of the President's mental health and the individual good of each family member.
However, I'll break tradition this once. It's not mandatory for women from outside Saudi Arabia to go veiled, but it's good for an American not to. She may not have felt she had much choice, given the constant rumors that her husband is a secret Muslim, but all the same it's a healthy signal of independence. It's good for us, and it's good for the women of Saudi Arabia.
