U-M's dean of the College of Engineering has accepted a leading position at Duke University.

(CNN) - US Border Patrol Chief Carla Provost said on Wednesday that she was a member of a secret Facebook group that reportedly contains vulgar and offensive posts, adding that she told internal investigators once she realized her involvement. Provost denied knowing of the "highly offensive and absolutely unacceptable posts" ahead of the ProPublica investigative report that first exposed the Facebook group dubbed "I'm 10-15." The name refers to Border Patrol code 10-15 for "aliens in custody." Earlier this month, The Intercept reported Provost was a member of the Facebook group. She said, "It is completely unacceptable and not representative of the border Patrol as a whole."
