WASHINGTON - After a day off because of the excitement surrounding their father's inauguration, President Barack Obama's two daughters are back in school.

Both girls returned to class Thursday at the private Sidwell Friends School.

Malia, 10, is a fifth-grader at the middle school campus in the District of Columbia, while younger sister Sasha, 7, is in second grade at the elementary school campus in Bethesda, Md., just outside Washington.

The girls were allowed to skip school on Wednesday after an exhilarating, late-night scamper around their new home that ended when they opened a White House door and found their favorite musical band, the Jonas Brothers, waiting to surpise them.

Barack Obama was sworn in as president on Tuesday.
