Presidents don't keep gifts given to them by foreign countries. They become property of the federal government.
At absolute best, the Trump library could pay market value to buy it from the government. Pretty unlikely.
It's been this way for a long long time.
BTW, that bribe from Ukraine went into a Biden family shell organization, while he was VP. In order to avoid the very rules I just laid out for you. Thanks for putting the two into such stark contrast for all of us. I don't think this was your intention, though.
Still time to delete this and pretend it was never posted...
