Couldn’t find what President Trump did other than fire a few and demote others.....am I missing something here?
You're missing that the Other Guy did absolutely nothing. At least President Trump's administration, against all odds, is beginning to chip away at the problem. Confucius say "Longest journey begins with the first step."
Read that he wants to suspend the Union and make it easier up and down the line to get rid of the bad ones. Do you have any idea of what sort of pressure he had to exert to fire as many as he has? It took me 14 months and 9 months respectively to fire the two I got rid of when I was a DoD Civilian..
