I feel it worths noting that the meaning of the word 'legal' is different for ears of western than some eastern nations. It may be inaccurate to describe for western minds what actualy is happening there as legality and law is an instrument of the ruling party for the benefit of the ruling party not some independent supervising power for the goodwill of all. I feel using the English word 'legal' is completely inaccurate expressing Russian public matters, some other was better to adapt/coin for the situation, unsure what though.
I believe you are confused and when you talk about where US is headed you wanted to cite the absolute presidential immunity that Trump pursuing for himself (adapting from his good friend, Putin) so he could continue doing and escaping the deserved consequences of huge tax evasions (plural!), fueling riot, stealing and exposing state and allied secrets, and in general other yet unspecified criminal activity as well as escalations and conflicts to destroy the order and peace in the whole population in order to pretend being a strong figure (in the attempt of cloacking weak personality), including asking Putin to attack the allies of US (being borderline to treason perhaps?).
What you call legal attack is actually called legal proceedings against a criminal.
