Susie Willies is the Chief of Staff of the President.
She controls his agenda. She sometimes takes decisions on his behalf.
She is one of the very few people that Donald Trump actually trusts.
In 2010, she helped healthcare businessman Rick Scott become Governor of Florida.
She went to create a corporate lobbying firm named Ballard Partners. She recruited Pam Bondi as a lobbyist for Ballard Partners.
In 2018, she helped Ron De Santis become Governor Governor of Florida.
In 2024, Susie Willies was the top campaign manager of Donald Trump.
Besides what the other commenter replied, with Trump there’s a special value in controlling his agenda because often the last person he talks to will have the most sway. There have been stories about his appointees taking advantage of a rival appointee being away or in a meeting, and getting Trump to issue an order or even just tweet a position on something so it’s harder to walk back when someone else gets his ear.
