In this Aug. 17, 2016, file photo, then-Republican presidential candidate Donald Trump participates in a roundtable discussion on national security in his offices in Trump Tower in New York, with Ret. Army Gen. Mike Flynn, left, Ret. Army Lt. Gen. Keith Kellogg. Trump's transition team is rich with lobbyists, a climate change-denier and an ex-federal prosecutor involved in the mass firings of U.S. attorneys. Kellogg has been working closely with Trump adviser Flynn, advising the Trump campaign on matters relating to foreign policy and national security.
