So while TSA agents pull nuns and people in wheelchairs aside for enhanced screenings a radical jihadist is working inside the airport itself.

MINNEAPOLIS (KMSP) – He was the second known American killed while fighting for ISIS in Syria, and the second from Minnesota — and a Fox 9 exclusive uncovering his employment history is raising a few eyebrows.

Before he died, Muhumed left behind a trail of selfies and questions. Who recruited him to join the terror group, and how did he support himself and 9 children? Multiple sources tell Fox 9 News that, for a time, he worked at a job that gave him security clearance at the airport, access to the tarmac and unfettered access to planes.
