President Barack Obama gave an emotional farewell speech in Chicago on Tuesday night as he was surrounded by his family, friends and supporters. However, the outgoing president’s younger daughter Sasha was not in attendance during his farewell address.

People took to Twitter to ask and speculate where was Sasha during her father’s final presidential speech. Several theories about the teen’s whereabouts cropped up on the micro-blogging website with one user joking Michelle Obama must have barred her from attending the event for “pulling a last minute wardrobe temper tantrum” like “most teens.”

The president also did not mention why his younger daughter remained absent from the event. He, however, said: “Malia and Sasha under the strangest of circumstances you have become two amazing young women. ... And you wore the burden of years in the spotlight so easily. Of all that I have done in my life, I am most proud to be your dad.”

So where exactly was Sasha at the time? A White House official told CBS News that the 15-year-old stayed back in Washington D.C. because she had an exam at school Wednesday morning.

Last March, the Washington Post reported that the Obamas would stay back in the capital once he leaves office so that Sasha can finish high school.

“We’re going to have to stay a couple of years so Sasha can finish” school, he said at the time over lunch with a small group of supporters in Milwaukee, Wisconsin. “Transferring someone in the middle of high school — tough.”

The Post also noted that Obama will be the first former president since Woodrow Wilson — almost a century ago — to stay back in D.C. after leaving the White House.

Obama’s older daughter Malia who graduated from high school last May, attended Tuesday’s farewell address. She will head to Harvard University this fall after a gap year.
