WASHINGTON (AP) - An administrative judge is set to begin hearing testimony on whether Virginia Tech should pay a $55,000 fine in connection to the 2007 shooting rampage on its campus.
 
University officials are expected to testify along with victims' families at the hearing that begins Wednesday.
 
The Education Department has said the school was too slow in notifying the campus of a safety threat. It says it violated the law by waiting more than two hours after two students were fatally shot in a dorm before sending out a warning by email. By that time, student gunman Seung-Hui Cho (sung-wee joh) was chaining shut the doors to a classroom building where he killed 30 more people and then himself.
