He's expanded the schools undergraduate and graduate programs and overseen nearly $450 million in construction efforts to grow BSU's campus — including adding the Honors College, alumni center and upcoming fine arts facility.Kustra was a former state lawmaker and lieutenant governor in Illinois before moving to Idaho. The Idaho State Board of Education will now begin searching for Kustra's replacement. The board is currently searching for two presidents to fill vacancies at Idaho State University and Lewis-Clark State College. Kustra says he and his wife, Kathy, "will be Broncos for life."
