It is pretty amazing - and at this point Trump might literally running out of competent attorney's, who are capable of representing him in this matter, and are still willing to do so.
To be clear, for those that don't know the intricacies of the legal field/community, most licensed attorneys do not have the experience nor ability to properly represent someone in this high profile of a case. Not because it's high profile, but because some of the areas of law are so complex and rare that it's hard to get experience - and some areas are completely new to the judicial system (i.e. Trump stealing classified documents).
