United States President Donald Trump has announced the resignation of Veterans Affairs Secretary David Shulkin and picked the presidential doctor to replace him.
Thanking Mr Shulkin in a tweet, he said he intended to nominate Rear Admiral Ronny Jackson, who gave him his first medical as president in January.
Unnamed officials told Reuters Mr Shulkin had become a distraction due to speculation about his future.
A Pentagon official, Robert Wilkie, will be the acting secretary.
It is the latest in a series of departures from Mr Trump’s cabinet.
This month alone, he has replaced his Secretary of State, Rex Tillerson, and National Security Advisor, HR McMaster, while his top economic adviser, Gary Cohn, also left following discord over Mr Trump’s plans to impose trade tariffs on steel and aluminium.
