President-elect Donald Trump began laying the groundwork on Friday to take office on Jan. 20, gathering the most loyal advisers from his insurgent campaign and three of his children to plot his transition strategy.

Trump put Vice President-elect Mike Pence in charge of his White House transition team, while demoting his former transition chief, tarnished New Jersey Gov. Chris Christie, to one of the six vice chair posts.

Daughter Ivanka and sons Eric and Donald Jr. and son-in-law Jared Kushner accounted for a quarter of the 16-member executive committee, which was filled with politicians and advisers who stuck with Trump during his roller-coaster first run for public office.
