First on CNN: Trump picks Kristi Noem to serve as his Homeland Security secretary

President-elect Donald Trump has selected South Dakota Gov. Kristi Noem as his next secretary of the Department of Homeland Security, according to two people familiar with the selection.

Noem will be tapped to take over the agency as two key immigration hardliners — Stephen Miller and Tom Homan — are slated to serve in senior roles, signaling Trump is serious about his promise to crack down on his immigration pledges. With his selection of Noem, Trump is ensuring a loyalist will head an agency he prioritizes and that is key to his domestic agenda.
