President-elect Donald Trump has picked Stephen Miller, a top policy aide from his campaign, to serve in the White House as senior adviser to the president for policy, the transition announced team Tuesday.

“Stephen played a central and wide-ranging role in our primary and general election campaign,” Trump said in a statement. “He is deeply committed to the America First agenda, and understands the policies and actions necessary to put that agenda into effect.”

Miller has served as Trump’s top policy adviser since January 2016. Miller previously worked for Sen. Jeff Sessions, another early Trump supporter and Trump’s pick for Attorney General.

“Stephen Miller is the best person President-elect Donald Trump could have chosen to be his senior advisor for policy,” Sessions said in a statement released by the transition. “He has understood the Trump Movement from the beginning and has a unique understanding of the very real and honest concerns of the American people.”

“I am deeply honored for the opportunity to serve the President-elect, and to focus efforts to develop critical policies that serve the national interest,” Miller said. “A Trump administration will focus unremittingly on the safety, security and economic well being of working Americans.”

Miller is one of just a few people, along with Reince Priebus and Steve Bannon, to be named to senior White House roles. While Trump has rapidly assembled a cabinet, much of his senior staff remains to be selected.
