The Senate voted on Saturday morning to confirm Kristi Noem as President Donald Trump’s Homeland Security secretary, installing a long-time Trump ally at the helm of an agency poised to play a central role in the president’s promised immigration crackdown.

The US Senate on Saturday confirmed South Dakota governor Kristi Noem to lead the Department of Homeland Security (DHS), a key agency in President Donald Trump's push to clamp down on illegal immigration.

Noem's role as Homeland Security secretary is expected to be more limited in scope than her predecessors’, sources familiar with the Trump transition tell NBC News.
