WASHINGTON (AP) — President-elect Donald Trump has named Susie Wiles, the manager of his victorious campaign, as his White House chief of staff.

She would be the first woman to hold the influential role.

Wiles is widely credited within and outside Trump’s inner circle for running what was, by far, his most disciplined and well-executed campaign.

She largely avoided the spotlight, even refusing to take the mic to speak as Trump celebrated his victory early Wednesday morning.
