Warmbier's doctors described him Thursday as being in a state of "unresponsive wakefulness" but declined to discuss his outlook for improvement, saying such information would be kept confidential.
On Monday, less than a week after returning to the United States with severe brain damage, his family announced Warmbier had "completed his journey home". Doctors say he opens his eyes and blinks spontaneously, but that there is no indication that he understands language nor does he respond to verbal commands.
Otto Warmbier has a severe brain injury and is in a state of "unresponsive wakefulness", his OH doctors said on Thursday.
Fred Warmbier, describing his son's return as "bittersweet", wore the same cream-color jacket that Otto wore when making his confession - a statement that he called "an incredible performance".
"We relied on this false premise that they would treat Otto fairly and let him go", he said.
The Warmbiers were told just a week ago that their son contracted botulism and fell into a coma shortly after being arrested and sentenced, in March past year.
"There is no reason for any civilized nation to keep his condition secret and deny him medical treatment for so long", Fred Warmbier said at a press conference in Cincinnati.
At the time the USA said it was working to secure Warmbier's release.
"Otto was just a really great lad who fell into the most horrendous situation that no one could ever believe", Gratton told the Post.
When asked whether then-President Barack Obama could have done more, Warmbier replied, "I think the results speak for themselves".
The University of Virginia student was later sentenced to 15 years of prison and hard labor for allegedly stealing a political propaganda poster from his Pyongyang hotel in January 2016. According to reports, his son is stable but has "suffered from severe neurological injury", Warmbier's father said. "So do we. We have few answers", Fred Warmbier said. "It was kind", Fred Warmbier said.
He returned to the U.S.in state of coma after being detained in North Korea for over 17 months. He was visiting North Korea with a tour group.
Tillerson said Tuesday that the State Department was continuing "to have discussions" with North Korea about the release of the other three imprisoned American citizens. A Young Pioneer Tours official told a news site that focuses on the region that only one person - Otto Warmbier - has ever been arrested among the 8,000-plus worldwide travelers who have taken part in the company's tours.
U.S. lawmakers introduced a bill last month that would ban United States citizens from travelling to North Korea as tourists and require them to obtain special permission for other types of visits, following the detention of at least 17 Americans there in the past decade. "I don't know what being in shock is, but I'm pretty sure I was", the father told assembled reporters in Cincinnati.
"We are extremely grateful for their efforts and concern", he said of Portman and the Trump administration. She says Yun traveled with the doctors to North Korea on a private aircraft after being instructed by President Donald Trump to travel there to negotiate Warmbier's release.
Warmbier is taken to North Korea's top court in Pyongyang North Korea.
This is at least the fifth trip to North Korea for the heavily pierced and tattooed former basketball star.
