Bassam Khalaf considers himself a rap artist. And until last week, he was also considered a federal employee. Khalaf was a screener at Bush Intercontinental Airport until someone in the federal government found out Khalaf is also known as the "Arabic Assassin" in the rap community. He was quickly fired afterwards.

But the federal government apparently didn't approve of his profanity-laced lyrics. That also included threats to blow up buildings with airplanes.
