Trump has ousted Secretary of State Rex Tillerson and plans to nominate CIA Director Mike Pompeo to replace him as the nation’s top diplomat, orchestrating a major change to his national security team amid delicate negotiations with North Korea, White House officials said Tuesday.

Trump last Friday asked Tillerson to step aside, and the embattled diplomat cut short his trip to Africa on Monday to return to Washington.

Pompeo will replace him at the State Department, and Gina Haspel — the deputy director at the CIA — will succeed him at the CIA, becoming the first woman to run the spy agency, if confirmed.

In a statement issued to The Washington Post, Trump praised both Pompeo and Haspel.

“I am proud to nominate the Director of the Central Intelligence Agency, Mike Pompeo, to be our new Secretary of State,” Trump said. “Mike graduated first in his class at West Point, served with distinction in the U.S. Army, and graduated with Honors from Harvard Law School. He went on to serve in the U.S. House of Representatives with a proven record of working across the aisle.”

The president continued, “Gina Haspel, the Deputy Director of the CIA, will be nominated to replace Director Pompeo and she will be the CIA’s first-ever female director, a historic milestone. Mike and Gina have worked together for more than a year, and have developed a great mutual respect.”
