President Donald Trump said Friday he will meet with Kim Jong Un in Singapore later this month after all, ending more than a week of uncertainty about whether direct denuclearization talks would go on.

Key North Korean official Kim Yong Chol — who is sanctioned over the 2014 Sony cyberattack — talked to Trump in the Oval Office for more than an hour on Friday and delivered a letter from the North Korean leader. In the letter, Kim Jong Un was expected to show interest in meeting with Trump, The Wall Street Journal reported.

Trump told reporters he does not expect the June summit — which was rescheduled after confusion, threats and then diplomacy — will lead to an agreement about Pyongyang dismantling its nuclear and missile programs. He said he sees a framework developing "over a period of time" and more than one meeting.

"I think it'll be a process," he told reporters after the meeting with the top North Korean aide. "I never said it goes in one meeting. I think it's going to be a process."

Secretary of State Mike Pompeo met with a North Korean delegation this week as the Trump administration discussed the possibility of holding the previously scrapped meeting between Trump and Kim. On Thursday, Trump tweeted that his administration had "very good meetings with North Korea."
