Good for Biden.
Trump should have fired at least 10 000 Executive Branch employees/appointees on January 21, 2017, and the fact that he did not is on him.
You can’t blame Biden (or whoever is issuing him his orders) for playing the game the way it should be played.
POTUS Trump did not come close to draining the swamp and actually put swamp around him. This was one reason he is not President right now.
