Who can Trump trust in DC? No one!
The only people who can serve Trump loyally are either outsiders or those on the fringe. This is a quite small pool of talent. Many of them also lack experience because they are not given the opportunity to do anything of significance.
So Trump, in many cases, has to rely on existing talents from swamp. However, they sabotage what he is trying to do at any time.
I have some suspicion that somebody sabotaged the plan of countering election fraud. Trump may have had a plan to deal with it, but somebody entrusted to carrying it out stabbed in the back. But this is just my speculation. I don't know this is how things went down.
