My evidence is the sudden flurry of self-righteous indignation from the Trump gang. Anyone else would have simply set the record straight and moved on. But Trump seems to be determined to use the incident to distract us from the rest of his crimes and treachery. He has established a behavioral pattern that is pretty predictable.
Like a kid accused of constant mischief, when he can finally point to an accusation against him that is unfair, he milks it for all its worth.

The careful control of disclosure, to only release the minimum amount of information only when forced to by the “fake” press is getting very old. This white house is about as transparent as a carefully constructed concrete block wall.

For them, this is a legitimate activity justified because it keeps the government from taxing your profits.
