OBL mission commander - OMG! He's a liberal arts major.

I did google lists of majors and "Liberal arts" as the name of an undergraduate major did not turn up.

Master of Liberal Arts (MLA), Master of Liberal Studies (MLS), Artium Liberalium Magister (ALM), and Doctor of Liberal Studies (DLS).

These are degree titles, not the area of focused study that the student has to choose. In the Harvard program you site, the student has to select from among 19 areas of focus. None of those is called "liberal arts."
