A document crafted by senior White House advisers, first reported by CNN, includes proposals to move the State Department’s Bureau of Consular Affairs and Bureau of Population, Refugees and Migration over to the Department of Homeland Security. White House policy adviser Stephen Miller, who helped craft the document, has reportedly been pushing Secretary of State Rex Tillerson to get “tougher” on immigration, vetting and refugee policy at the State Department.

One White House official cautioned that these proposals resulted from a brainstorming session focused on improving efficiencies across government and were far from being approved. Another White House official told me that if Tillerson doesn’t go along with changes that Miller and others in the White House are pushing the State Department to implement internally, the plan to strip Foggy Bottom of its role supervising these functions could gain traction.
