A White House official confirmed that Sasha was at home in Washington, D.C., studying for a school exam the next day.

Though Sasha was not there in person, President Obama still gave a touching tribute to both his daughters during his speech.

"Malia and Sasha, under the strangest of circumstances, you have become two amazing young women. Of all that I have done in my life, I am most proud to be your dad," the president said.

He is likely even more proud that his daughter prioritized her schoolwork over her father's important farewell speech.

Sasha, 15, attends Washington, D.C.’s Sidwell Friends School. Her older sister Malia graduated from high school last year and will enroll at Harvard in the fall of 2017.
