CINCINNATI — Unlike President Donald Trump, Otto Warmbier’s parents don’t believe North Korea’s leader.

The parents of the American college student who was sent home from North Korea in a vegetative state spoke out Friday, after Trump’s comment this week that he takes Kim Jong Un “at his word” that he was unaware of any mistreatment during the young man’s 17 months of captivity.

Warmbier died at age 22 soon after his return in June 2017.

Fred and Cindy Warmbier, who have expressed appreciation of Trump in the past and were guests at his 2018 State of the Union address, said in a statement Friday they had been respectfully silent while Trump and Kim met in Vietnam — but no longer.

“Kim and his evil regime are responsible for the death of our son Otto. Kim and his evil regime are responsible for unimaginable cruelty and inhumanity,” they said. “No excuses or lavish praise can change that.”

White House counselor Kellyanne Conway said Friday on the Fox News show “America’s Newsroom” that Trump has “deep affection” for the Warmbiers, shares their grief and agrees North Korea is responsible.

But, she said, Trump is saying “there’s no indication Chairman Kim knew what happened to Otto Warmbier when it happened.”

Democratic Sen. Chuck Schumer, of New York, said in a tweet that Trump owes the Warmbiers an apology for “simply deciding to take a cruel and brutal dictator at his word.”

Warmbier’s parents have accused North Korea of torturing the University of Virginia student, who was detained for allegedly stealing a propaganda poster as he prepared to end a visit to the country with a tour group.

Fred Warmbier described to Fox News in 2017 Otto’s condition when he returned: making an “involuntary, inhuman sound,” “staring blankly into space, jerking violently,” and blind and deaf.

Doctors in Cincinnati said he had suffered severe brain damage, although they weren’t sure what led to it. North Korea denied mistreating him, saying he fell into a coma that resulted from botulism and a sleeping pill.

A federal judge in December ordered North Korea to pay more than $500 million in a wrongful death suit filed by Warmbier’s parents.
