Kristi Noem was confirmed by the US 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.
Noem, who was governor of South Dakota, shares Trump's hardline immigration views and called illegal immigration an "invasion" during a confirmation hearing earlier this month.
She was confirmed by a vote of 59 to 34 in the Republican-led Senate.
