President Trump shared a quotation on social media, making it clear it was one he wanted people to absorb: “He who saves his Country does not violate any Law.”
This is a classic expression of monarchist power, much like《L'état, c'est moi》
I would say that's what he meant but from the other side. I don't read this as him excusing himself. I read it as a message to the followers who may "do something"
