When Trump was asked who he was consulting with on foreign policy, he could only specify himself. Of any others, he said, “I listen to a lot of people, I talk to a lot of people, and at the appropriate time I’ll tell you who the people are, but I speak to a lot of people, but my primary consultant is myself, and I have a good instinct for this stuff.”

Trump went on to make similar remarks about his “large brain” after becoming President.
