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

Susie Wiles has years of political experience working behind the scenes but now will be in the spotlight as President-elect Donald Trump’s closest adviser and confidant.

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.”
