WASHINGTON, June 2 (Reuters) - U.S. President Donald Trump said on Sunday that White House Council of Economic Advisers Chairman Kevin Hassett will "shortly" leave his post, but did not provide a reason for the latest high-level departure from the administration.

"Kevin Hassett, who has done such a great job for me and the Administration, will be leaving shortly. His very talented replacement will be named as soon as I get back to the U.S.," Trump said in a Twitter post on Sunday night as he flew to Europe for a series of state visits.

Trump thanked Hassett for his work, and called him a "true friend" in the Twitter post on Sunday.
