(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. On Friday, Attorney General Mark Herring said the university agreed to withdraw its appointment of former federal judge and prosecutor Mark Filip as independent counsel to investigate how the school responds to rape allegations.
