President-elect Donald Trump has made his first security leadership choices. He plans to nominate Republicans Rep. Mike Pompeo of Kansas as director of the Central Intelligence Agency and Alabama Sen. Jeff Sessions as Attorney General.

He has also offered the position of national security adviser to retired three-star Gen. Michael Flynn, a dogged advocate and campaign adviser for Trump.

NPR national security editor Phil Ewing (@philewing) speaks with Here & Now's Meghna Chakrabarti about Flynn's background and how it could shape U.S. foreign policy and security.
