Vice President-elect Mike Pence will lead President-elect Donald Trump's transition team, replacing New Jersey governor Chris Christie.
Mr Trump picked his transition chairman and other leaders on Friday.
It was his biggest staffing announcement since he won the election this week.
Mr Christie will now serve as vice chairman.
He is joined on the executive committee by former house speaker Newt Gingrich, retired neurosurgeon Ben Carson, Lieutenant General Michael Flynn, former New York mayor Rudolph Giuliani and Alabama senator Jeff Sessions.
A statement says more than a dozen other people will also advise Mr Trump on transition matters.
They include some of Mr Trump's children, Republican Party chairman Reince Priebus and former Breitbart news executive Steve Bannon.
Everything I am, everything I will ever be, I owe God, my parents, my family and the state of Indiana. Thank you for a warm homecoming. pic.twitter.com/Rn1BPOo3hf— Mike Pence (@Mike_Pence) November 11, 2016
