Michael O’Brien’s resignation was announced in a Thursday email from the university president defending the school’s financial well-being. The day after KSAT reported on a $4 million budget shortfall at the Texas A&M University-San Antonio, a top official is stepping down. Provost and Vice President for Academic Affairs Mike O’Brien has stepped down from his post “effective immediately,” according to an email University President Cynthia Teniente-Matson sent to faculty and staff Thursday. The president said O’Brien would remain as a faculty member after a brief sabbatical. The announcement was at the bottom of a lengthy email in which Teniente-Matson defended the school’s financial management and level of student enrollment.
