To date, yes, his backers always seem to come away from the evidence saying that Trump was either maligned or within his rights as a businessman to do as he did. To me, it's not clear if this proves that Trump is a master self-promoter or if his followers are so determined to oust a Democratic administration that they would be willing to accept anything he does as 'good presidential material'. Some of this continued support may be explained by the psycho/social concept of "reactance"... when a person's allegiance to an idea (or candidate) is actually deepened by criticism of them. This tendency toward reactance is higher in males, who are overly concerned with being defeated anyway... so they double down when their hero is attacked. It's totally emotional reasoning.
Upon release of the Trump University documents, he attacked the Judge ("we think he is Mexican"), and slammed the news media for covering the whole affair plus the business of his donations to Veterans causes.. That was one interesting press conference, putting on display several points about his personality. First and foremost, he flatly threatens to be vindictive and retaliate if he assumes the office of President. Donald will seek revenge on his enemies by the use of any means at his disposal.
On a positive note for Trump, Paul Ryan did weakly endorse him today....following yesterday's ringing endorsement by Kim Jong Un... so it appears true that Donald is truly uniting people from broad swaths of the political spectrum. Go Donald.
