• President Donald Trump received a letter North Korean leader Kim Jong Un at the White House on Friday
• While the actual letter was not seen publicly, a North Korean official also presented Trump with a symbolic, oversized novelty envelope, and the two men took a picture with it in the Oval Office.
• Trump later teased the contents of the letter, but told reporters in the afternoon that he hadn't yet opened it.
• US officials with knowledge of the letter's contents said it did not make any noteworthy threats or concessions, and was seen as a positive gesture.

President Donald Trump received what he called a "very nice" letter from North Korean leader Kim Jong Un on Friday.

While the actual letter was not seen publicly, North Korean vice chairman Kim Yong Chol presented Trump with a symbolic, oversized novelty envelope, and the two men took a picture with it in the Oval Office.

Trump later teased the contents of the letter, but told reporters he hadn't yet opened it.

"That letter was a very nice letter," Trump said to reporters. "Oh, would you like to see what was in that letter. How much? How much?"

"I haven't seen the letter yet. I purposely didn't open the letter," Trump said. "I could be in for a big surprise, folks."

North Korea made a similar gesture with its neighbor to the south in February, during the Winter Olympics.

Kim Yo-jong delivered a personal letter to South Korean President Moon Jae-in on behalf of her brother, Kim Jong Un at the time.

Kim Yong Chol, who delivered the letter to Trump on Friday, also met with Secretary of State Mike Pompeo.

US officials with knowledge of the letter's contents said it did not make any noteworthy threats or concessions, and was seen as a positive step, according to multiple news reports.

Trump is scheduled to meet Kim Jong Un in Singapore on June 12, which will mark the first time a sitting US president will meet face-to-face with a North Korean leader.

After a brief escalation in rhetoric between the US and North Korea in May, Trump announced in a letter that he was cancelling the summit. He reversed course after Pyongyang said it was willing "to sit down face-to-face with the US and resolve issues anytime and in any format."
