WASHINGTON – National security adviser John Bolton Sunday distanced himself from President Trump’s decision to side with North Korean leader Kim Jong Un, who denied involvement in the death of US college student Otto Warmbier.

Asked if he believes the North Korea dictator as well, Bolton told CNN’s “State of the Union:” “The president takes him at his word. My opinion doesn’t matter.”

Bolton, a foreign policy hawk, said he’s no longer a “Fox News contributor” who will pontificate from the sidelines.

“I don’t do that anymore,” Bolton said. “I give my advice to the president. I give my opinions to the president. He makes up his own mind. That’s why he’s president.”

Bolton brushed off the flurry of North Korean experts who believe Kim would have full knowledge of what happened to a high-profile US prisoner.

“Good for them,” Bolton said.

Trump shocked Washington and upset the Warmbier family when he said he didn’t condemn Kim for the death of Warmbier, the 22-year-old who was imprisoned in North Korea in 2016 and died the following year being returned to the US in a vegetative state.

“He tells me that he didn’t know about it and I will take him at his word,” Trump said during a news conference last week in Vietnam.

Warmbier’s parents spoke out after Trump returned home after his summit with the North Korean leader.

“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. No excuses or lavish praise can change that,” they said.

Republicans and Democrats alike couldn’t understand why Trump continued to publicly side with autocrats like Russian leader Vladimir Putin, Kim Jong Un and Saudi Crown Prince Mohammed bin Salman.

“This president has consistently been willing to override the advice of the intelligence community,” Sen. Mark Warner (D-Va.) said on CNN Sunday. “Instead, this president seems to choose the word of dictators over the words of our intelligence community.”

“I wouldn’t have said it,” Rep Peter King told The Post last week about Trump’s North Korean comments. “One reason he could be saying it is to keep the process going. … I certainly don’t believe him. Nothing happens in North Korea, certainly to an American citizen, without Kim Jong Un knowing about it. He obviously knew about.”

Bolton said Trump’s public acquiesce could be part of a broader strategy to get a “full accounting” from North Korea on what happened to Warmbier.

“What he’s trying to convey is that he that he’s got a difficult line to walk to negotiate with Kim Jong Un,” Bolton said on “Fox News Sunday.”

“It doesn’t mean he accepts it as reality,” Bolton added. “It means he accepts that’s what Kim Jong Un said.”
