Kim Jong Un was not responsible for horrific injuries sustained by American student Otto Warmbier, who died shortly after being released from 17 months of detention in North Korea, President Donald Trump said Thursday at a press conference after the nuclear summit in Hanoi collapsed.

“Some really bad things happened to Otto — some really really bad things. But he tells me that he didn’t know about it and I will take him at his word,” Trump said, referring to the North Korean dictator.

Warmbier, 22, was arrested for taking a propaganda banner from a hotel while on a visit to Pyongyang in January 2016. The University of Virginia student from Ohio was later sentenced to 15 years of hard labor.
