Story highlights

"He is a man of tremendous talent and tremendous experience," Trump said of McMaster.

Trump's first choice, retired Vice Adm. Robert Harward, turned the job down over concerns about how the White House was being run, sources told CNN.

(CNN) —  

President Donald Trump announced Monday that Lt. Gen. H.R. McMaster will serve as his next national security adviser, filling the void left last week by the sudden dismissal of Michael Flynn.

McMaster, the head of the Army Capabilities Integration Center, will become one of Trump’s top national security and foreign policy advisers, taking the helm of the White House’s National Security Council, which was left rudderless after Flynn was forced to resign after just 24 days on the job.

Retired Lt. Gen. Keith Kellogg, who had been serving as the acting national security adviser since Flynn’s exit, will return to his role as chief of staff of the National Security Council.
