Peña Nieto: My position has been and will continue to be very firm saying that Mexico cannot pay for that wall.
Trump: But you cannot say that to the press. The press is going to go with that and I cannot live with that. You cannot say that to the press because I cannot negotiate under those circumstances.
From an economic issue, it is the least important thing we were talking about, but psychologically, it means something so let us just say “we will work it out.”
