By the end of Trump's first year in office, 34 percent of his original staff had resigned, been fired, or been reassigned.[429] As of early July 2018[update], 61 percent of Trump's senior aides had left[430] and 141 staffers had left in the previous year.[431] Both figures set a record for recent presidents—more change in the first 13 months than his four immediate predecessors saw in their first two years.[432] Notable early departures included National Security Advisor Flynn (after just 25 days in office), and Press Secretary Sean Spicer.[432] Close personal aides to Trump including Bannon, Hope Hicks, John McEntee, and Keith Schiller quit or were forced out.[433] Some, including Hicks and McEntee, later returned to the White House in different posts.[434] Trump publicly disparaged several of his former top officials, calling them incompetent, stupid, or crazy.[435]
Trump had four White House chiefs of staff, marginalizing or pushing out several.[436] Reince Priebus was replaced after seven months by retired Marine general John F. Kelly.[437] Kelly resigned in December 2018 after a tumultuous tenure in which his influence waned, and Trump subsequently disparaged him.
