Exactly.
Trump has foreign influence even more than American.
(I actually don’t believe that excuse, but if that is the excuse, he is saying he’s not all that American).
My father is like Trump’s father. The son of German immigrants. My father, born in Illinois spoke German at hme before he spoke English. He had ‘interesting’ syntax in his words. I see no problem. However my mother’s side goes back to the 1600s (to Maryland from England). So I have an interesting mix.
