President-elect Donald Trump’s roster of transition team and possible cabinet members just got shorter thanks to national security advisors Lt. Gen. Michael Flynn and Lt. Gen. Keith Kellogg.

Update: Mattis Named Trump’s Defense Secretary »

According to NBC News, the list, originally curated by New Jersey Gov. Chris Christie, Sen. Jeff Sessions of Alabama, and Sessions’ chief of staff, Rick Dearborn, was significantly cut down by Flynn, Kellogg, and Trump’s inner circle of family members and friends.

On Nov. 17, NBC reported that Flynn crossed out a number of leading candidates for national security and intelligence positions endorsed by Christie and Sessions, including Marine Gen. James Mattis, Marine Gen. Peter Pace, Navy Adm. William McRaven, and former House Intelligence chairman Mike Rogers.

Flynn, who is still under consideration for National Security Adviser, did not respond to NBC News’ request for comment.
