WASHINGTON (AP) " President Donald Trump says there's only one person in charge of his immigration policy: Him.

Trump was asked as he was leaving the White House Wednesday whether he had ever considering tapping his influential aide, Stephen Miller, to lead the department in the wake of Kirstjen Nielsen's departure.

Trump says Miller is an "excellent guy' and a "brilliant man," but said, "Frankly, there's only one person that's running it: You know who that is? It's me."

Trump has picked United States Customs and Border Protection commissioner Kevin McAleenan to serve as acting secretary. Asked whether he might keep him on permanently, Trump said he likes McAleenan "a lot" and that it "could happen."

He adds that, "right now" McAleenan is "the man."
