POTUS is half German and half Scottish, just like the Queen of England.
His mother’s family is the Macleod clan.
They have a number of tartans, one primarily yellow with black stripes and another green with black stripes.
The green one reminds me a little of the Kekistan flag.
The yellow one reminds me of the canary yellow gown with cape (no stripes though) that the First Lady wore in England.
His family crest is a castle.
