Former CIA agent Valerie Plame is scheduled to speak to University of Alabama students and screen a documentary about her experiences. University officials say Plame will speak with students of Stephen Schwab, a UA adjunct assistant professor and former CIA analyst, when she visits the Tuscaloosa campus March 31. She's also expected to screen the film at 7:30 p.m. March 31 in Farrah Hall. That event is free and open to the public. Lewis "Scooter" Libby Jr., who was Vice President Dick Cheney's former chief of staff, was convicted and sentenced for lying and obstructing the investigation into the leaking of Plame's name to the media. President George W. Bush later commuted Libby's sentence, sparing him from a 2 1/2-year prison term. Bush left intact a $250,000 fine and probation.
