Approximately 98% of the 34,000 students at BYU are Mormon; two-thirds of its American students come from outside the state of Utah. In addition to its undergraduate program, BYU offers graduate degrees in 47 departments and includes two professional schools: the Marriott School of Management and the J. Reuben Clark Law School. BYU has approximately 370,000 living alumni. Over 26 BYU graduates have served in the U.S. Senate and U.S. House of Representatives, such as former Dean of the U.S. Senate Reed Smoot (class of 1876). Cabinet members of American presidents include former United States Secretary of Agriculture to President Dwight D. Eisenhower, Ezra Taft Benson '26 and Rex E. Lee '60, who was U.S. Solicitor General under President Ronald Reagan. Mitt Romney, former Governor of Massachusetts and 2008 and 2012 Republican presidential nominee, was valedictorian of his class in 1971. [citation needed]
