A longtime personal assistant to President Donald Trump was reportedly fired and escorted out of the White House on Monday, with one report claiming the ouster was due to a criminal investigation.

John McEntee was unceremoniously removed from his position because the Department of Homeland Security is investigating him for serious financial crimes, CNN reported, citing an unidentified source familiar with his termination. The alleged crimes are said to not be related to Trump.

The Wall Street Journal , which was the first to break the news of McEntees ouster, reported that he was removed because of an unspecified security issue, citing an unidentified White House official.

McEntee wasnt allowed to collect his belongings including his jacket before being escorted out, according to the Journal.

The DHS did not immediately respond to a request for comment.
