​President Trump ​said he received a “​beautiful” and “very warm” letter from North Korean leader Kim Jong Un and suggested they could meet for their third summit.

​​“We have a very good relationship together​ ​… I think something will happen, but in the meantime, we have our hostages back​,” Trump told reporters on Tuesday as he prepared to leave the White House for a campaign stop in Iowa. “We have a very good relationship.”

​The president said the two leaders ​could meet again without providing any details.

“In the meantime, he’s kept his word​,” Trump said. “That’s very important to me.​”

Trump walked out of their second summit in February when discussions about denuclearizing North Korea ​​fell apart over the removal of sanctions.
