WASHINGTON/ABOARD AIR FORCE ONE - US President Donald Trump said on Tuesday his second summit with Deomratic People's Republic of Korea (DPRK) leader Kim Jong-un would be held after US congressional elections on Nov 6.

Earlier on Tuesday, Trump told reporters that he thought "incredible" progress had been made in US talks with DPRK

Speaking to reporters as he flew to Iowa for a political rally, Trump said: "It’ll be after the midterms. I just can't leave now."

Earlier on Tuesday, Trump told reporters that plans were being made for his second summit with Kim and that he thought "incredible" progress had been made in US talks with DPRK.

He said Secretary of State Mike Pompeo had very good talks with Kim over the weekend and that three or four locations were being considered.

Pompeo echoed Trump's comments when he spoke briefly to reporters during a Tuesday afternoon visit to the White House.

"While there's still a long way to go and much work to do,we can now see a path where we will achieve (our) ultimate goal, which is the full and final verified denuclearization of North Korea," he said. The DPRK is also referred to as North Korea.

Trump and Kim held a historic first summit in Singapore on June 12 at which Kim pledged to work toward denuclearization of the Korean peninsula. His actions have fallen short, however, of Washington's demands for a complete inventory of its weapons and facilities and irreversible steps to give up its nuclear arsenal, which could threaten the United States.

'NO ROCKETS FLYING'

Still, Trump was upbeat on progress so far.

"You got no rockets flying, you have no missiles flying, you have no nuclear testing," Trump said in the Oval Office. "We've made incredible progress - beyond incredible.

"But I have agreed to meet," he said. "We have a very good relationship with Chairman Kim. I like him, he likes me, the relationship is good."

Pompeo said on Monday the two sides were "pretty close" to agreeing on details for a second summit.

He added that Kim had said he was ready to allow international inspectors into DPRK's Punggye-ri nuclear testing site and the Sohae missile engine test facility as soon as the United States and DPRK agreed on logistics.

DPRK is very interested in reaching some sort of agreement on denuclearization so that it can grow economically with the benefit of the foreign investment closed to it now, Trump said.
