Funniest example of this double standard that I've seen recently is the treatment of Ronny Jackson, Trump's pick to head the VA. Criticism of him and his supposed actions as White House physician have popped up all over the place. The funny part is that everything he's accused of doing happened (or more likely didn't happen) while he was serving as physician during the Obama administration. Nothing he did was a problem to anyone until he was about to become a prominent member of a Republican administration.
