WASHINGTON (Reuters) - President Donald Trump was expected to nominate Kirstjen Nielsen, who as the top aide to his White House chief of staff has sought to instil order in Trump's team, to lead the U.S. Department of Homeland Security, a White House official said on Wednesday.
If confirmed by the Senate, Nielsen would take the reins at a sprawling department with more than 240,000 employees that is responsible for U.S. border and airport security, immigration policy, disaster response, refugee admissions and other matters.
