President Donald Trump is touting statistics showing declining rates of illegal immigration to the U.S.
Presiding over the ceremonial swearing-in of Kirstjen Nielsen as secretary of homeland security, the president says "the numbers have been so incredible."
Nielsen's nomination was confirmed Monday by the Senate. Trump says, "you're going to take it to new levels."
Vice President Mike Pence administered the oath of office, with much of the West Wing senior staff joining Nielsen's family to watch.
Nielsen spoke briefly before reporters were escorted from the room, thanking acting-secretary Elaine Duke, who had filled the vacancy created when John Kelly was elevated to become Trump's chief of staff.
