Trump says North Korea summit will happen

President Trump got a visit today at the White House from North Korea's senior official, Kim Yong Chol, who hand delivered a letter by Kim Jong Un to the President.

The large envelope containing a letter from Kim Jong Un to President Trump was “carefully examined” for toxins and anything potentially dangerous before it arrived at the White House, a White House official said.

The United States Secret Service examined the letter off-site before Kim Yong Chol, a former spy chief and currently North Korea's top nuclear negotiator, arrived at the White House, the official said.

Here's a look at the envelope:

Dan Scavino Jr., President Trump's social media director, just tweeted a photo of North Korea's senior official, Kim Yong Chol, delivering a letter by Kim Jong Un in a large envelope to the President.

In his tweet, Scavino misspelled the North Korean leader's name.

Here's what the envelope looked like:

President Trump has now read the letter from North Korea leader Kim Jong Un that was hand delivered by a top North Korean envoy this afternoon, a White House official says.

North Korea's senior official, Kim Yong Chol, met with Trump earlier today at the White House for more than an hour.

Moments after the meeting, he told reporters that he hadn't yet opened the letter. Here's that moment:

Senate Majority Leader Mitch McConnell said he would advise President Trump on the North Korea talks to “be interested in the details," but cautioned him not to fall in love with the deal.

"You have to not want the deal too much," he said.

McConnell's comments came in an appearance at a conference in Louisville.

He said he expects talks with the North Koreans to be challenging.

“I think you can anticipate the North Koreans making every effort they can to get sanctions and other relief, and give up as little as possible," McConnell said. "It's going to be quite a challenge. And I think for these situations to work, you have to not want the deal too much."

President Trump said his administration had readied "hundreds of new sanctions" to tighten the pressure campaign on North Korea, but said he has opted to hold off on additional sanctions while talks are still ongoing.

"We had hundreds of new sanctions ready to go on," Trump said.

But he explained he decided the US is "not going to put them on until such time as the talks break down."

North Korea's senior official, Kim Yong Chol, just met with President Trump to hand deliver a letter written by Kim Jong Un.

But the President said he hasn't seen the letter yet.

"I purposely didn't open the letter," he said. "I haven't it opened it yet. I didn't open it in front of the director. I said, 'Would you want me to open it?' He said, 'You can read it later.'"

Trump joked:
