Trump is a billionaire. Making note of such gifts would be like being called to account for a bag of peanuts someone once gave you.
Even if it could be shown that he took them, there is such a thing as a good faith assumption under the law. He may have thought that one of us underlings took care of it for him and he was free to take them.
It’s only a matter of contacting him and make it right and all is good.
And he also donated his entire salary during his 4 years in office to various organizations
As he had to do was turn them over to the appropriate agency. They belong to the federal government not him. He knows that.
