Inside the mysterious rise of Ezra Cohen-Watnick, the young NSC official at the center of a bizarre Russiagate subplot.

McMaster is joining the White House staff with views on Russia, counterterrorism, strengthening the military and other major security issues that diverge not only from those of the Trump loyalists, but also from those the president himself has expressed.

His views are incompatible with Trump's "bombing the shit out of them."

Will Trump's new national security adviser be able to ply his Vietnam lessons in the White House?

He also named retired U.S. Army General Keith Kellogg, who had been serving as acting national security adviser, as chief of staff to the National Security Council.
