Prior to her appointment as Principal Deputy Chief of Staff, Doyle served as Chief of Staff to
Mick Mulvaney when he was Director of the
Office of Management and Budget. She previously served as Government Relations Manager for the
Ford Motor Company, as a legislative assistant to Mulvaney when he was a Member of the
House of Representatives, and as a legislative assistant to
Senator Pat Toomey. At a February 2020 meeting with President Trump and Mulvaney, Doyle objected to Trump's plan to appoint
John McEntee as Director of Presidential Personnel. "Mr. President, I have never said no to anything you've asked me to do, but I am asking you to please reconsider this. I don't think it's a good idea," she said. Trump responded by screaming, "You people never fucking listen to me. You're going to fucking do what I tell you to do." On April 20, 2020, it was announced that Doyle would leave her position as White House Deputy Chief of Staff to become the Deputy Chief of Staff for Policy in the
Office of the First Lady. == Personal life ==
