In shakeup, US vice-president-elect Mike Pence to head Donald Trump transition team

Donald Trump shook up his White House transition team today, appointing running mate Mike Pence to head the process of filling key administration posts, and demoting New Jersey Governor Chris Christie to a deputy role.

"The mission of our team will be clear: put together the most highly qualified group of successful leaders who will be able to implement our change agenda in Washington," the president-elect said in a statement as his team gathered in Trump Tower in New York.

Republican National Committee chairman Reince Priebus, as well as three of Trump's grown children, Donald Trump Jr, Eric Trump and Ivanka Trump, will sit on the transition team's executive committee, he said.
