When President Trump shakes hands with Kim Jong Un on Tuesday morning, it will mark the first time that a sitting U.S. president comes face to face with a North Korean leader. Trump once dubbed Kim "Little Rocket Man" and threatened "fire and fury" against his regime, but has expressed optimism about a potential deal with North Korea on denuclearization. "I just think it's going to work out very nicely," he said Monday. But he has also said he is prepared to walk away from the table if talks are not fruitful.

David Douglas Duncan went everywhere and took extraordinary pictures at every stop.

Duncan, who died Thursday in the south of France at age 102, was one of the greatest photojournalists of the 20th century.

When Mike Pompeo became CIA director last year, he immediately set his sights on North Korea and its opaque nuclear program.

"Within weeks of me coming here, I created a Korea Mission Center, stood it up with a senior leader who had just retired, brought him back to run the organization," Pompeo said in January.

The White House has nominated Navy Adm. Harry Harris to be the U.S. ambassador to South Korea, filling a key post that's been vacant for the first 16 months of the Trump presidency.

The Senate intelligence committee voted 10-5 Wednesday to recommend Gina Haspel as CIA director despite the controversy surrounding her role in the agency's waterboarding program.

The full Senate now appears all but certain to confirm Haspel within the next week or so, which would make her the first woman to lead the CIA.

Her confirmation also would complete President Trump's recent shakeup of his national security and foreign policy teams.

The Pentagon said Thursday that an investigation into the deaths of four American soldiers in Niger last year found "individual, organizational and institutional failures." But it said no sole reason was responsible for the ambush.

Gina Haspel's appearance before the Senate intelligence committee on Wednesday promises to be a very unusual confirmation hearing.

Most every nominee for a top government job has a long public record that is open for scrutiny. Not so with Haspel, who would be the first woman to lead the CIA.

When Michael Hayden ran the CIA and the National Security Agency, his public comments were largely confined to congressional testimony. Now that he's retired, "I'm on Twitter and I'm on CNN," said Hayden.

He was also the featured guest as dozens of former national security officials and several current ones spoke at a recent conference on threats the U.S. faces.

When U.S. troops were ambushed in Niger last October, the widespread reaction was surprise: The U.S. has military forces in Niger? What are they doing there?

The Pentagon has started briefing the families of four soldiers killed in an ambush in Niger last October, and the military acknowledges a series of missteps contributed to the deaths, one family member told NPR.

"I think in any instance where people lose there lives, there were obviously mistakes that were made," said Will Wright, the brother of one of those killed, Staff Sgt. Dustin Wright. Will Wright is himself a combat veteran, having served as a staff sergeant in Afghanistan. He and his family were briefed by military officers on Thursday.
