I've worked with people who did their jobs magnificently, and competently.
Who knows what kind of people they are when they are off work. And I didn't care.
What I cared about is when we are at work. We have a job to do.
Trump is not afraid to fire you. No matter who you are. Or how loyal, or how much "history" you've had with him in the past. Working with Trump, you do your job. Or you are out.
So this guy Mark Robinson and Guiliani may be in Trumps entourage right now, but they are in no way protected from their work performance, unlike how a certain current administration won't hold accountable for any actions what their people have been doing the past 3 1/2 years.

I don't believe there are any Knights in Shining Armor or Joan of Arc's in today's political arena. That's why I focus on policy and job performance.
