The Transportation Security Administration says it is seeking to fire seven Philadelphia International Airport workers it says were involved in a bribery scheme.
The agency said Friday its decision comes after an eight-month investigation.
Ten employees were removed from their duties in November amid allegations they gave money to a training instructor in exchange for passing annual proficiency exams.
Three resigned, and the TSA said it plans to fire the other seven.
Former TSA training instructor Shannon Gilliam pleaded guilty in February in federal court to taking a $200 bribe from a Philadelphia security officer. He was sentenced to 300 hours of community service and six months of house arrest.
