P resident-elect Donald Trump’s first key appointment since his victory this week came with a historic choice. He selected Susie Wiles to be his White House chief of staff, making her the first woman appointed to the position.

The first female White House chief of staff is a longtime Florida operative and onetime aide to moderate Republicans who is “more about strategy than ideology.”

President-elect Donald Trump on Thursday named co-campaign chair Susie Wiles as his White House chief of staff, one of the most important nonelected posts in Washington. She will be the first woman in that role.

Donald Trump announced that Susie Wiles, one of his two campaign managers, will be his White House chief of staff, entrusting a top position to a political operative who helped him win the presidency.

After helping engineer Donald Trump’s improbable and sweeping victory in the presidential race, Susie Wiles, the president-elect’s unassuming co-campaign chief, is seen as the frontrunner to become his White House chief of staff, according to six sources familiar with discussions inside the campaign.

Wiles was widely credited with orchestrating Trump's political comeback. Wiles will be the first woman to serve as White House chief of staff.
