Kristi Noem, South Dakota's firebrand Republican governor, faced questioning Friday at her confirmation hearing to be secretary of homeland security. Noem, the daughter of a farmer and a former representative from South Dakota, is being questioned before the Senate Homeland Security and Governmental Affairs Committee.

When it comes to immigration, which normally falls under the Department of Homeland Security, Kristi Noem would take direction from two other people, sources tell NBC News.
