Warmbier was sentenced to 15 years hard labor for allegedly stealing a propaganda poster from a hotel in North Korea in January 2016.
Americans are regarded as enemies in North Korea because the two countries never signed a peace treaty to formally end the 1950-53 Korean War.
When asked if he would bring up the cases of Warmbier and three other Americans detained in North Korea, Rodman told reporters, "That's not my objective right now". The announcement came shortly after former National Basketball Association player Dennis Rodman arrived in Pyongyang for a return visit to North Korea.
My colleagues Anna Fifield and Karen DeYoung reported that there was no coordination between Rodman and the White House: "Officials involved in securing Warmbier's release told The Post that it had nothing to do with Rodman's trip to Pyongyang, calling it a "bizarre coincidence" that might have been a deliberate ploy from North Korea to distract from Warmbier's condition".
Asked if he had spoken to Trump about his trip, he said, "Well, I'm pretty sure he's pretty much happy with the fact that I'm over here trying to accomplish something that we both need".
While North Korea's move to free Warmbier could potentially provide an opening for talks on security issues, the prospects still appear bleak.
"FILE â€" In this February 29, 2016 file photo, American student Otto Warmbier speaks to reporters in Pyongyang, North Korea. He was charged with "hostile acts against the state".
Otto Warmbier, an American student who was detained in North Korea in January 2016 and lapsed into coma in March soon after his trial, was released by the Pyongyang regime on humanitarian nrounds.
He was sentenced in March 2016 after a televised tearful public confession to trying to steal a propaganda banner. On this trip, he has already been roundly criticized by some for visiting during a time of high tensions between the US and North Korea over its weapons programs and recent missile launches.
As the Americans continued to push for the Swedish diplomats to see all four, North Korea's ambassador to the United Nations urgently requested a meeting with Yun in NY, according to Trump administration officials, who spoke on the condition of anonymity about the still-secret arrangements.
A senior Trump administration official told Fox News Rodman was going to the North "as a private citizen". "Take care of Otto", Trump is said to have instructed his top diplomat. "My objective is to go over there and try to see if I can keep bringing sports to North Korea".
Tillerson says that Warmbier is on his way back to the U.S.to be re-united with his family. Officials said he was to stay until Saturday. "American and medical officials would get out".

The Warmbier family released a statement Tuesday saying they are grateful their son will finally be home with the people who love him.
Yun arrived in Pyongyang early Monday with two American physicians.
But the important thing in the immediate future is Mr. Warmbier's health.
The latest visit comes amid high tensions between Washington and Pyongyang - which is now holding 4 Americans - following a series of missile tests by the North, which have triggered tightened United Nations sanctions.
The North Koreans later urgently requested another meeting in NY, and Yun met North Korea's ambassador to the United Nations on June 6, when he was told about Warmbier's "condition", the official said, speaking on condition of anonymity.
During his detention, Leigh said he was provided with one meal a day, and slept on a blanket on the floor.
"Otto has been terrorized and brutalized for 18 months by a pariah regime in North Korea", the father said in an interview scheduled to air Thursday night. Thousands of USA troops are based in South Korea, and the Demilitarized Zone between the North and South is one of the most heavily fortified borders in the world.
Here's his latest foray into North Korean diplomacy.
Since March previous year, Otto Warmbier was in a coma.
The US state department said it had secured his release "at the direction" of President Trump but it then emerged that Mr Warmbier has been in coma for more than a year after contracting botulism - a fate his family learnt about a week ago.
Democratic Sen. Sherrod Brown said "North Korea's despicable actions in detaining and holding Otto were unacceptable and must be condemned".
