Trump's 2020 Republican campaign announced Tuesday that he will serve as a senior adviser for campaign operations.
President Trump's re-election campaign manager Brad Parscale announced Mr McEntee's hiring on Tuesday. He was soon hired to a full-time position. Just as with Rob Porter, who got bounced from his job a few weeks ago, McEntee appeared to have near-universal access to the president.
He made headlines during Trump's May visit to Saudi Arabia as the "man in red tie".
The White House's revolving door for high-ranking staffers has grown so notorious that President Trump's staunchest allies can't defend the chaos. During presidential trips, Mr. McEntee and the White House doctor were two aides who were never left off the travel manifest.
White House spokeswoman Sarah Huckabee Sanders declined to comment on the reasons for his departure, saying only Mr McEntee was going to the campaign. It wasn't clear why McEntee, a well-liked figure in the White House, had been dismissed, and campaign aides weren't given a reason.
His duties included ensuring Trump always had a marker on hand to sign autographs, transmitting messages to him at the White House residence and making sure the clocks there were moved forward for daylight-saving time over the weekend, according to the Journal.
In response to news reports about Mr McEntee's exit, Elijah Cummings, the top-ranking Democrat on the House Oversight Committee, sent a letter to chief of staff John Kelly requesting all documents related to Mr McEntee's employment and departure.
However, CNN later reported that McEntee was, uh, facing a federal investigation over unspecified "serious financial crimes". "The White House's ongoing obstruction of congressional oversight appears to be an attempt to hide from the American people pervasive and widespread dysfunction inside the White House, which directly threatens our nation's security".
