President Trump is happy with White House chief of staff John Kelly's first day, in which combative White House communications director Anthony Scaramucci was removed from his position.

"A great day at the White House!" Trump tweeted Monday night.

The day was headlined by Scaramucci's departure from the White House less than 10 days after Trump announced he was hiring him.

Multiple reports said Kelly asked for Scaramucci to be removed as a way to impose full authority over his staff.

Scaramucci's brief tenure was marked by controversy.

Scaramucci vowed to tamp down on the leaks coming out of the White House and threatened to fire the entire White House staff to eliminate the unauthorized spread of information coming out of the West Wing.

Scaramucci also went on a profanity-laced tirade with a reporter for the New Yorker, targeting former White House chief of staff Reince Priebus and White House chief strategist Steve Bannon.

Priebus resigned as chief of staff last week, and Kelly was sworn in to replace him Monday.
