(KRON/AP)—-President-elect Donald Trump has picked Republican National Committee chairman Reince Priebus as his chief of staff and conservative media executive Stephen Bannon as his senior counselor.

Trump’s campaign team made the announcement Sunday.

This comes as Trump is trying to establish his administration before heading to the White House.

In selecting Priebus, Trump is turning to a Washington veteran with deep ties to Republican leadership, particularly House Speaker Paul Ryan.

Bannon ran the conservative website Breitbart before joining Trump’s presidential campaign during the general election. Neither has significant governing experience.

“I am thrilled to have my very successful team continue with me in leading our country,” Trump said. “Steve and Reince are highly qualified leaders who worked well together on our campaign and led us to a historic victory. Now I will have them both with me in the White House as we work to make America great again.”
