CHARLOTTESVILLE, Va. (AP) -- The University of Virginia on Saturday suspended activities at all campus fraternal organizations amid an investigation into a published report in which a student described being sexually assaulted by seven men at a fraternity in 2012. President Teresa Sullivan said in a letter to the university community that the Board of Visitors is scheduled to meet Tuesday to discuss the allegations contained in a Rolling Stone article, along with the university's policies and procedures concerning sexual assaults.
