The Senate voted on Saturday to confirm Kristi Noem as homeland security secretary, putting a former South Dakota governor in charge of the department at the heart of President Trump’s agenda to crack down on immigration. The vote was 59 to 34, and she was sworn-in on Saturday afternoon by the Supreme Court Justice Clarence Thomas.
