Michael Flynn's replacement - three possibilities

Last Updated Feb 14, 2017 12:57 PM EST

The White House is considering three candidates to serve as President Trump’s national security adviser after Gen. Michael Flynn’s resignation from that position Monday night.

Officials have floated three names, including retired Lt. General Joseph Keith Kellogg, Jr., who’s been named acting national security adviser in the interim.  Former CIA Director David Petraeus and Vice Admiral Bob Harward, who’s a retired Navy SEAL and a former deputy commander of CENTCOM, or U.S. Central Command, are the other two names.

CBS News’ Major Garrett reports Kellogg is viewed more as a placeholder than a permanent solution, and Petraeus is under serious consideration, but he’s not yet considered a front-runner. Defense Secretary James Mattis will be a key voice in the process to replace Flynn as he has worked closely with both Harward and Petraeus.

Speaking to NBC’s “Today,” top Trump adviser Kellyanne Conway confirmed there are “three candidates, very strong candidates that will be considered for a permanent position here.”

Joseph Keith Kellogg Jr.

Kellogg had been serving as chief of staff and executive secretary of the National Security Council when Flynn resigned. He is a former commander of the 82nd Airborne Division and served as chief operating officer for the Coalition Provisional Authority in Baghdad after the U.S.-led invasion in 2003, according to The Washington Post. He also worked at Oracle, CACI International and Abraxas, according to the Post.

Bob Harward

Harward worked under Defense Secretary James Mattis when Harward was deputy commander of CENTCOM from 2011 to 2013. He previously served as deputy commanding general for operations of Joint Special Operations Command at Fort Bragg in North Carolina. Harward has also commanded troops in both Iraq and Afghanistan for six years after the 9/11 attacks. Under President George W. Bush, he served on the National Security Council as director of strategy and policy for the office of combating terrorism.

David Petraeus

Petraeus, who served as President Obama’s CIA director from 2011 to 2012, has a long history in counterinsurgency tactics and strategy. Mattis also supported Petraeus during the Trump transition period when Petraeus was under consideration for secretary of state. Petraeus also led U.S. forces in Afghanistan, succeeding Stanley McChrystal, and also served as commander of CENTCOM.
