I think so. I think she was summoned and is acting as a bag lady. Consider:
1. The trip came out of nowhere.
2. The trip is a serious political liability.
3. She is missing her husband’s birthday to go.
4. No media will be allowed to cover her activities.
I used to be suspicious what came back on Air Force One when the Clinton’s went to China and elsewhere. In Michelle’s case, its beyond suspicion. I bet foreign intel agencies (France for example) will monitor her meetings.
