Personal aide McEntee escorted out of the building WASHINGTON »

President Donald Trump’s personal assistant was removed from his job this week, leaving the president more isolated amid a growing exodus of many of his most trusted aides.

John McEntee, who served as the president’s personal assistant, was escorted out Monday, according to two people close to the White House who spoke on condition of anonymity in order to discuss private conversations.

One of a shrinking group of former campaign aides still working in the West Wing, McEntee quickly rejoined the president’s campaign. Trump’s 2020 Republican campaign announced Tuesday that he will serve as a senior adviser for campaign operations.

White House spokeswoman Sarah Huckabee Sanders declined to comment on the reasons for his departure, saying only that McEntee was going to the campaign.
