Gavin Newsom, who has supported a variety of restrictions in order to slow the spread of Covid, was caught blatantly violating his own rules, attending a dinner with a large number of unrelated people, sitting close together, not wearing masks. He claimed it was outdoors, but that turned out to mean a room that had glass doors to the outside which were closed because the dinner party was a noisy one. He has been suitably apologetic, conceded that it was something he ought not to have done.
There are two possible interpretations of his behavior, depending on whether one regards the primary function of masks as protecting the wearer or protecting everyone else. If it is protecting the wearer, than his behavior is strong evidence that he doesn't believe in the claim on which his rules are based, since he was willing to do without that protection for himself. At least, he doesn't believe in it for men in their late fifties — and there has been no suggestion in the rules he imposed that they only apply to those of us sixty-five and over.
If one believes, perhaps more plausibly, that the primary function is protecting other people, than his behavior is evidence that he is a hypocrite, willing to impose on other people risks that he forbids them from imposing on each other, but not that he does not believe the claim those rules are based on.
A third possibility is that he is merely a snob, someone who believes in his heart, although he would never say, that pandemic diseases only infect his social inferiors.
