NBC News reports:
The White House is strongly considering Chad Wolf, the acting undersecretary for strategy at the Department of Homeland Security and former chief of staff to then-Secretary Kirstjen Nielsen, to head DHS, according to four current and former department officials familiar with deliberations on the matter.
Wolf is not considered as hard-line on immigration as two other names floated for the job — acting Director of U.S. Citizenship and Immigration Services Ken Cuccinelli and acting Commissioner of Customs and Border Protection Mark Morgan — but internal emails obtained by NBC News show Wolf was an early architect of the migrant family separation policy at the southwest border.
As far back as December 2017, when Wolf was acting chief of staff to Nielsen, he sent a list of 16 options to curb the number of undocumented immigrants to Gene Hamilton, counselor to then-Attorney General Jeff Sessions, for review. Number two on the list: “Separate family units.”
