"We hold North Korea accountable for Otto Warmbier's unjust imprisonment, and demand the release of three other Americans who have been illegally detained". His final public appearance came last March in a show trial, where following a tearful courtroom confession, he was handed a 15-year jail sentence with hard labor. Doctors in his hometown of Cincinnati, Ohio said the 22-year-old had suffered severe brain damage while in North Korea, but that it was not clear what caused it.
Warmbier was on a tourist trip when he was arrested and sentenced in March previous year. "It's a brutal regime, and we'll be able to handle it", the president said.
A United States student released from North Korea in a coma after over a year being held in the country has died - with his distraught family accusing the brutal regime of "torturous mistreatment".
The University of Virginia student wept at his sentencing, saying: "I have made the worst mistake of my life".
His parents said they were only informed of his condition a week ago.
Warmbier was leaving North Korea on January 2, 2016, when he was detained at the airport.
Warmbier, who was returned to the U.S. last week, had reportedly been in a coma since March 2016. He was visiting North Korea as a tourist.
"He looked very uncomfortable - nearly anguished. The U.S. government should not just throw up its hands and say, 'This is just how North Korea is.' But how do you do that in a smart way where there is some modicum of accountability?"More news: Netizens make fun of Jared Kushner's voice

"But at least we got him home to be with his parents where they were so happy to see him, even though he was in very tough condition". Otto Warmbier, serving a 15-year prison term for alleged anti-state acts, was released to his home state of OH on Tuesday in a coma. But within a day the countenance of his face changed and he was at peace. But we choose to focus on the time we were given to be with this remarkable person.
The Warmbier family confirmed on Monday that he had died.
"Considering these facts and this tragic outcome we will no longer be organising tours for U.S. citizens to North Korea".

"There had not been any previous detainment in North Korea that has ended with such tragic finality", the company said.
Speaking at a public event on Friday, Donald Trump took credit on behalf of his administration for getting Warmbier back.
Medical tests carried out last week in the United States offered no conclusive evidence as to the cause of his neurological injuries, and no evidence of a prior botulism infection.
Warmbier was "generous, outgoing, sweet, smart as a whip, just an overall good guy", Danica White, his sophomore English teacher, recalled last week. He was released June 13 on humanitarian grounds after claims by North Korean authorities that he took a sleeping pill and never recovered consciousness.
