Trump, speaking to reporters on the White House lawn Tuesday before leaving on a campaign trip to Iowa, was asked about Kim Jong Nam’s spying, which was first reported by the Wall Street Journal.

“I don’t know, I have not heard about that,” the president said, before contradicting himself and assuring Kim Jong Un that his administration wouldn’t do anything so underhanded.

“I saw the information about the CIA with respect to his brother or half brother, and I would tell him that would not happen under my auspices, that’s for sure,” Trump said. “I wouldn’t let that happen under my auspices.”
