Trump, speaking at the Nevada GOP convention in Las Vegas, touted his relationship with North Korea since taking office.

"We have a good chemistry together," Trump said. "We have a great chairman, Kim, we have great chemistry." ADVERTISEMENT

In his speech, Trump said that during his 2016 presidential campaign, families of soldiers who were lost in the 1950s during the Korean War approached him to ask if he could get back the remains of their loved ones.

“As we’re negotiating different points the other day in Singapore, I asked Chairman Kim if we could do that,” Trump said. "I will do that," Trump said of Kim.

During this month's summit with North Korea, Trump said Kim agreed to return U.S. war remains. The Associated Press reported earlier this week that the U.S. military command in South Korea is preparing to receive the remains of an unknown number of soldiers from North Korea.

U.S. military officials said they moved 100 coffins to the Demilitarized Zone earlier on Saturday to prepare for North Korea’s return of the remains, CNN reported.
