Donald Trump’s personal assistant John McEntee escorted from the White House in the cold without his jacket

President Donald Trump's personal assistant John McEntee was escorted out of White House Monday but it's unclear why.

According to the Wall Street Journal, two administration officials confirmed McEntee was canned, however, press secretary Sarah Huckabee Sanders refused to comment.

“We don’t comment on personnel issues," she said.

McEntee was one of the longest-serving aides to Trump and his position dates back to the early days of the campaign. Prior to that, it was mostly the president's family that surrounded him, along with Stephen Miller, Dan Scavino and Hope Hicks.

He wasn't well known in public but was constantly beside Trump for the last three years. His responsibilities consisted of having markers for Trump to sign autographs, delivering messages to the residence and ensuring the clocks in the White House residence were adjusted for daylight-savings.

“It’s not going to be great for morale,” an official said.

Officials also said he was escorted to the building even without his jacket. He indicated to his colleagues it may have been about his background check.

According to Paris Dennard, a Republican operative and close ally to Trump, McEntee will now rejoin the campaign team along with Katrina Pierson.

"It was announced today by the Trump Campaign that John McEntee will re-join the team and serve as the new Senior Advisor for campaign operations based in D.C." he tweeted.

A Politico story from 2017 cited McEntee's fondness of forging the president's signature. He said at the time it was totally for fun, though.

“For context, it’s about having fun,” a former White House staffer said quickly as an explanation. “Not trying to undermine the U.S. government.”
