The University of Virginia chapter of Phi Kappa Psi said Monday that the fraternity house will file a lawsuit against Rolling Stone, calling the magazine’s discredited reporting of an alleged gang rape by some of its members “reckless.” The lawsuit comes a day after Rolling Stone editors retracted a Nov. 19 story, “A Rape on Campus,” that presented a chilling account of a brutal sexual assault that allegedly occurred in the Phi Kappa Psi house at U-Va. in 2012.
