After Donald Trump insisted he’ll make Mexico pay for his border wall despite their preemptive refusal, Wolf Blitzer asked if he’ll continue pressing the issue even if it sparks a trade war.

“You know, I don’t mind trade wars,” Trump responded. “We’re losing so much with Mexico and China, with China, we’re losing $500 billion a year.”

Trump cited as examples new factories from Carrier, Ford, and Nabisco that Mexico ”took.” To fight back, Trump said he’s boycotting Oreos.
