The Senate voted 59 to 34 to confirm Ms. Noem, the governor of South Dakota, as the new head of the Department.

The role is key to Trump’s plans for the second term after his pledge to deport millions of undocumented immigrants and impose a crackdown at the U.S.-Mexico border.

Kristi Noem was confirmed by the U.S. Senate as President Donald Trump's Homeland Security secretary on Saturday, putting into position a key member of the Republican's Cabinet as he launches a wide-ranging immigration crackdown.
