I have gone through all the reports regarding this issue. This is what I learned.
1. The dance company had rented the space last January.
2. All the children are white..... video at the bottom of this article http://www.usatoday.com/story/theoval/2013/12/05/obama-american-university-ballet-company/3877009/
3, Obama insisted the interview be in front of college students http://lonelyconservative.com/2013/12/childrens-nutc*****r-rehearsals-scrapped-to-accommodate-tinglesobama-interview/
4. The university, although stating they will compensate, did not offer an apology

Some will say, so what kids get over things easy and no harm was done. To those people I say, you have never rehearsed for a play or been a dancer. To cram two days of work into the same day as the performance is not easy and can do physical harm. The children (not all ages was given, but the "Mouse" is only 7) will be tired! When you are tired, you make mistakes, mistakes in dance can result in broken ankles, legs, striated muscle tissue, dehydration. Then people will say, well an interview with the president does not happen all the time. Again, you do not watch TV; he is always in campaign mode and not a day passes without seeing him making a speech--little wonder that the congress complain that he does not meet with them. An alternative site could have been arranged, why did it have to be in front of college students....oh ya, Obamacare is failing because college age kids are not participating as required. So, next you will complain that I made an issue of the dance company being white children. Think about this, would he have bumped a black dance company? And really, I am not the only one who thinks that he is NOT impartial. But, that is for another time.
