Johnny McEntee called in White House liaisons from cabinet agencies for an introductory meeting Thursday, in which he asked them to identify political appointees across the U.S. government who are believed to be anti-Trump, three sources familiar with the meeting tell Axios.

Behind the scenes: McEntee, a 29-year-old former body man to Trump who was fired in 2018 by then-Chief of Staff John Kelly but recently rehired — and promoted to head the presidential personnel office — foreshadowed sweeping personnel changes across government.

But McEntee suggested the most dramatic changes may have to wait until after the November election.

Trump has empowered McEntee — whom he considers an absolute loyalist — to purge the “bad people” and “Deep State.”

McEntee told staff that those identified as anti-Trump will no longer get promotions by shifting them around agencies.

The backstory: Several administration officials have already been targeted in a post-impeachment blitz.
