US Homeland Security adviser Tom Bossert has resigned in the latest of a string of administration departures, the White House confirmed.
President Donald Trump “is grateful for Tom’s commitment to the safety and security of our great country,” White House spokeswoman Sarah Sanders said.
His exit comes just a day after former UN Ambassador John Bolton took over as Mr Trump’s national security adviser.
The White House statement on Tuesday did not include a reason why Mr Bossert was leaving.
