Our normal process, Madam Chair, is to go back to the airport when we've suspended a security clearance. The airport then talks to the regional CATSA person to make sure that the database connection is immediately disconnected so that pass will not show up accurately if they try to go into a secure area. Secondly, they take action to remove the pass, get it back from that employee, and ensure that it's been recovered.
I can't speak to the specifics. It may be something you want to ask at the next meeting. Normally, that would be something that someone in the airport in the security group would know. That may not mean that they would share those names with other people in the airport management.
