This one is another giant bag of unpossible given the high caliber screening processes in place for the hiring process of their employees. Well here in the real world we know better than to trust statements like that.
A Transportation Security Administration agent was arrested this week on
federal charges for her role in an alleged phony marriage scheme that
sought to secure U.S. citizenship for her purported spouse, a Lebanon
The federal criminal complaint does not detail Taha’s alleged motive for
taking part in the sham February 2002 marriage (or whether she was paid
in return for the marriage vows). Taha, charged with conspiracy and
making false statements, has worked as a TSA agent at the Detroit
airport since late-2002.
So in other words she was helping bring people into the country by marrying them. She dated other agents while supposedly being married, and even fathered a child with said TSA agents.
This is completely unsurprising, but never the less how did it escape their crack team of investigators?
Because your job as a federal agent is to break the law, just ask the ATF or DEA.
