U.S. President Donald Trump said he would be "very disappointed" if North Korea is resuming nuclear testing after his recent meeting with North Korean leader Kim Jong Un.

Trump made the comments to reporters Friday as he prepared to travel to Alabama to view tornado damage. He said he has greatly improved U.S. relations with North Korea during his time in office.

"Look, when I came in," he said, "under the Obama administration, North Korea was a disaster. You were going to war, folks, whether you know it or not … I inherited a mess."

He continued, "Right now you have no testing, you have no nothing. Let's see what happens, but I would be very disappointed if I saw testing."
