From a story on axios.com by Jonathan Swan headlined “Trump’s revenge”:

President Donald Trump was attending the National Prayer Breakfast, but showing no sign of grace. Lips pursed, face alternating between anger and frustration, he lashed out at enemies who had brought him to the doors of impeachment. He brandished the day’s newspapers, waving them above his head. The first headline: “ACQUITTED.” The next: “Trump Acquitted.” It was Feb. 6, 2020.

Close aides believed Trump had crossed a psychological line during his Senate trial. He now wanted to get even; he wanted to fire every single last “snake” inside his government. To activate the plan for revenge, Trump turned to a young take-no-prisoners loyalist with chutzpah: his former aide John McEntee.
